The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more. This wid… ...

Then, once the size of MIT's diode for light is scaled down -- it's currently around 400nm long, some 20 times larger than a transistor -- we might begin to see photonic circuits in computers ...

With simultaneous optical and electrical excitations, we experimentally demonstrate an active diode for the terahertz waves consisting of a graphene–silicon hybrid film.

Power Integrations Automotive-Qualified Qspeed Silicon Diodes Feature Lowest Qrr for Efficient, High-Switching-Speed Designs. These 600 V 12 A diodes can replace SiC components in automotive ...
