Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity ...

This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

The most demanding component in terms of high-frequency operation on an RF-ID tag is the rectifying device: this device needs to be able to charge a storage capacitor providing quasi-d.c. power supply ...

This image shows a state-of-the-art design of GaN p-n junction diodes that has resulted in near-unity ideality factor, avalanche breakdown capability, and record-breaking power performance. Insets ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

Modern ADAS cameras and similar systems require higher pixel counts to meet demand for greater precision. This has created a growing concern -- the risk of damage caused by photovoltaic voltage ...

Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode" may ...
