Devices called “PIN diodes” are commonly used as variable dynamic resistances in variable attenuators for RF and microwave applications. Driven to conduct such and so many milliamperes DC, they can ...

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 ...

Conjugated polymers and small molecules, as typically used in organic light-emitting diodes (OLEDs) or solar cells, are undoped semiconductors. When these semiconductors are sandwiched between two ...
