Single Molecule Electronics and Devices

Despite living in a world full of electronics gadgets, electronics still retains a veil of mystery. The workings mechanisms of electronic projects seem so abstract, as nothing can be seen working away to make gadgets work. Without moving gears, shafts and the like, nothing is visually happening on the printed circuit board.

You cannot see current flowing, only the results from it. As such, taking up electronics making as a hobby seems like a daunting feat for many would-be electronics project makers. Building something without the complete understanding of the theory behind it seems unthinkable. But in reality, it is possible to build projects with little understanding of the theory behind it.

While knowledge of electronics theory will prove itself to be more than helpful, it is not an essential part of building simple yet useful projects. A good way to get started is to first familiarize with the components used on a circuit board and their functions.

Similar to how cities work, the components on a PCB work together to form a complete system to power our devices. Once you think along these lines, the notion of having so many different components on a PCB will no longer seem too foreign an idea. To help you get started, we will introduce 15 commonly used electronic components mounted on Printed Circuit Boards! Resistors are one of the most commonly used components in PCBs and are probably the simplest to understand.

Their function is to resist the flow of current by dissipating electric power as heat. These rings are a code that indicates their resistance value. If you are unsure of how to do so, check out our article on deciphering resistor color codes!

Capacitors are the next most common component you will find on a PCB, and are usually outnumbered only by resistors. The function of capacitors is to temporarily hold electric charge, and release it whenever more power is needed elsewhere in the circuit. Typically, it does this by collecting opposite charges on two conductive layers separated by an insulating, or dielectric, material.

Capacitors are often categorized according to the conductor or dielectric material, which gives rise to many types with varying characteristics from high capacitance electrolytic capacitors, diverse polymer capacitors to the more stable ceramic disc capacitors. Some have appearances similar to axial resistors, but the classic capacitor is a radial style with the two leads protruding from the same end. Inductors are the last in the family of linear passive components, along with resistors and capacitors.

Like capacitors, they also store energy but instead of storing electrostatic energy, inductors store energy in the form of a magnetic field that generates when current flows through them.

The simplest inductor is a coil of wire. The greater the number of windings, the greater the magnetic field and therefore inductance. You may find them wrapped around a magnetic core that comes in a variety of shapes. This serves to amplify the magnetic field substantially and therefore, the stored energy.

Inductors are often used to filter out or block certain signals, for example, blocking interference in radio equipment or used in conjunction with capacitors to manipulate AC signals in switched mode power supplies. Potentiometers are a form of variable resistor.

They are commonly available in rotary and linear types. By rotating the knob of a rotary potentiometer, resistance is varied as the slider contact is moved over a semi-circular resistor. A classic example of rotary potentiometers is the volume controller on radios where the rotary potentiometer controls the amount of current to the amplifier.

The linear potentiometer is the same, except that resistance is varied by moving the slider contact on the resistor linearly. They are great when fine tuning is required in the field. The function of transformers is to transfer electrical energy from one circuit to another, with an increase or decrease in voltage.

Similar to inductors, they consist of a soft iron core with at least two coils of wire wound around it — the primary coil, for the first, or source circuit, and the secondary coil for the circuit where energy is being transferred to. You may have seen large industrial transformers on telegraph poles; these step-down the voltage from overhead transmission lines, typically several hundred thousand volts, to the few hundred volts typically required for household use.

It does this by having zero resistance in one direction and high resistance via the other direction. This feature can be used to block current from flowing in the wrong direction, which could cause damage. The most popular diode with hobbyists is the light-emitting diode or LED. Transistors are considered the fundamental building blocks of modern electronics.

Several billions may be found in a single IC chip. But transistors are simply amplifiers and electronic switches. They come in several types, with the bipolar transistor as the most common type. Bipolar transistors have 3 pins — the base, collector and emitter. For an NPN type, when a current usually a small current flows through from the base to the emitter, then it turns on another circuit that causes current usually much larger to flow from the collector to the emitter.

In a PNP transistor, the directions are reversed. Another type of transistor, called Field effect transistors, or FETs, use an electric field to activate the other circuit.

Also known as thyristors, Silicon Controlled Rectifiers SCR are similar to transistors and diodes — in fact, they are essentially two transistors working together. They also have three leads but consist of four silicon layers instead of three and only function as switches, not amplifiers.

Another important difference is that only a single pulse is required to activate the switch, whereas current has to be applied continuously in the case of a single transistor. They are more suited to switching larger amounts of power. ICs, or integrated circuits are exactly that, they are circuits and components that have been shrunk down onto wafers of semiconductor material.

The sheer number of components that can be fit onto a single chip is what gave rise to the first calculators and now powerful computers from smartphones to supercomputers. They are usually the brains of a wider circuit. The circuit is typically encased in a black plastic housing which can come in all shapes and sizes and have visible contacts, whether they are leads extending out from the body, or contact pads directly under like BGA chips for example. Crystal oscillators provide the clock in many circuits that require precise and stable timing elements.

They produce a periodic electronic signal by physically causing a piezoelectric material, the crystal, to oscillate, hence the name. Each crystal oscillator is designed to vibrate at a specific frequency and are more stable, economical and have a small form factor compared to other timing methods.

For this reason, they are commonly used as precise timers for microcontrollers or more commonly, in quartz wristwatches. A basic and easily overlooked component, the switch is simply a power button to control the current flow in the circuit, by switching between an open or a closed circuit.

They vary quite a bit in physical appearance, ranging from slider, rotary, push button, lever, toggle, key switches and the list goes on. Similarly, a relay is an electromagnetic switch operated via a solenoid, which becomes like a sort of temporary magnet when current flows through it.

They function as switches and can also amplify small currents to larger currents. Sensors are devices whose function is to detect changes in environmental conditions and generate an electrical signal corresponding to that change, which is sent to other electronic components in the circuit. Sensors convert energy from a physical phenomenon into electrical energy, and so they are in effect, transducers convert energy in one form into another.

They can be anything from a type of resistor in a resistance temperature detector RTD , to LEDs detecting in-fared signals, such as in a television remote. A wide variety of sensors exist for various environmental stimuli for example humidity, light, air quality, touch, sound, moisture and motion sensors.

The manufacture of integrated circuits with single-molecule building blocks is a goal of molecular electronics. While research in the past has been limited to bulk experiments on self-assembled monolayers, advances in technology have now enabled us to fabricate single-molecule junctions. This has led to significant progress in understanding electron transport in molecular systems at the single-molecule level and the concomitant emergence of new device concepts. Here, we review recent developments in this field. We summarize the methods currently used to form metal-molecule-metal structures and some single-molecule techniques essential for characterizing molecular junctions such as inelastic electron tunnelling spectroscopy. We then highlight several important achievements, including demonstration of single-molecule diodes, transistors, and switches that make use of electrical, photo, and mechanical stimulation to control the electron transport. We also discuss intriguing issues to be addressed further in the future such as heat and thermoelectric transport in an individual molecule. Miniaturization of electronics devices has been progressed rapidly owing to the advanced silicon technology for integrating billions of silicon-based building blocks in a millimeter-scale chip.

Printed electronics is becoming increasingly important in a variety of newly emerging areas. However, restricted to the rather limited conductive inks and available printing strategies, the current electronics manufacture is usually confined to industry level. Here, we show a highly cost-effective and entirely automatic printing way towards personal electronics making, through introducing a tapping-mode composite fluid delivery system. Fundamental mechanisms regarding the reliable printing, transfer and adhesion of the liquid metal inks on the substrate were disclosed through systematic theoretical interpretation and experimental measurements. With this liquid metal printer, a series of representative electronic patterns spanning from single wires to desired complex configurations such as integrated circuit IC , printed-circuits-on-board PCB , electronic paintings, or more do-it-yourself DIY devices, were demonstrated to be printed out with high precision in a moment.

Perspectives on Electronic and Photonic Materials

Three-dimensional 3D printing now enables the fabrication of novel 3D structural electronics and microfluidics. However, conventional subtractive manufacturing processes for MEMS fabrication relatively limit device structure to two dimensions and require post-processing steps for interface with microfluidics. Thus, the objective of this work is to create an additive manufacturing approach for fabrication of 3D microfluidic-based MEMS devices that enables 3D configurations of electromechanical systems and simultaneous integration of microfluidics in a one-pot manufacturing process. Here, we demonstrate the ability to fabricate microfluidic-based 3D microelectromechanical systems MEMS that contain orthogonal out-of-plane piezoelectric sensors and actuators using additive manufacturing. The devices were fabricated using a microextrusion 3D printing system that contained integrated pick-and-place functionality. Additively assembled materials and components included 3D printed epoxy, polydimethylsiloxane PDMS , silver nanoparticles, and eutectic Gallium-Indium as well as robotically embedded orthogonal out-of-plane piezoelectric chips lead zirconate titanate PZT. Electrical impedance spectroscopy and finite element modeling studies showed the embedded PZT chips exhibited multiple resonant modes of varying mode shape over the 0 — 20 MHz frequency range.
