While we’re 100 years past Edison’s fear, uncertainty, and doubt campaign, the fact of the matter is that DC is a bit easier ...

Researchers from the University of Colorado Boulder and NREL have uncovered a hidden weakness in perovskite solar cells that could explain why these promising materials fail under stress. By ...

Researchers in the United States have found microscopic pinholes in perovskites are responsible for the breakdown of such solar cells when under reverse bias conditions. They say the findings should ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Abstract: Within the field of radio-frequency identification (RFID) research, tunnel diodes have traditionally been researched for extending backscatter read-ranges for ultra-high-frequency (UHF) RFID ...

Abstract: I–V characteristics of Schottky barrier diodes (SBDs) in low forward bias and reverse bias voltages are critical in low-power and high-speed SBD-based circuits. Accurate modeling of I–V in ...

Miniature AlGaN-based diodes integrate light-emission and light-detection into a single device Applications in solar-blind comms, high-resolution imaging, biosensing, and environmental monitoring ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
