Diodes allow electricity to flow in only one direction, helping circuits work safely and correctly. This video explains how ...

The physicist William Shockley is perhaps today best known for three things: his role in the invention of the transistor, his calamitous management of Shockley Semiconductor which led to a mass ...

For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs ...

The mid-infrared (MIR) range of the electromagnetic spectrum can be indirectly accessed by frequency upconversion. Here, authors propose a phase-matching-free scheme for broadband and efficient ...

Abstract: Graded p-n junctions that can be fabricated by solidstate diffusion are low-loss nonlinear capacitors at microwave frequencies. These diodes can be used to make low-noise amplifiers, ...
