The basics of bipolar devices are covered, including basic semiconductor physics, [1] the concepts of electron and hole flow in semiconductors, the differences between drift and diffusion flow, ...

This file type includes high-resolution graphics and schematics when applicable. When devices are being designed to operate at low voltage, it’s often necessary to take into account the voltage drop ...

A global discovery born from the analysis of defective products: Tunneling effect, artificial superlattices, and Management ...

A superconducting strip allows more superconducting current to flow in one direction than in the other—achieving a stronger diode effect than previous devices. The new superconducting diode design ...

A physicist has made the best ever p-n junction diode from a carbon nanotube. The current-voltage characteristics of the device exhibit an "ideality factor" of one, which is the maximum possible value ...

The superconducting diode effect allows for nonreciprocal, dissipationless transport. It has the potential to enhance transfer current efficiency compared to the traditional semiconducting equivalent ...

The invention of blue light-emitting diodes has been awarded the 2014 Nobel Prize in physics. Blue LEDs, when combined with red and green diodes, produce an energy-efficient and environmentally ...

An array of nanochannels—made from a mixture of hydrophobic and hydrophilic materials—acts as a one-way diode for fluids. A diode is a common electronic component that restricts current flow in one ...

This year's Nobel Prize in physics goes to researchers whose findings you probably rely on just about every day (or, if you're like me, just about every minute). The blue light-emitting diodes they ...
