The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one ...

Across the United States, political polarization has deepened to historic levels. In a report published in May 2025, the Pew ...

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 ...

Abstract: This paper presents a compact, actively reconfigurable nonreciprocal metasurface based on a ferrite-loaded C-ring structure with PIN diode switching. The design integrates a planar ...

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 ...

[Dhananjay Gadre] happened across a useful little trick the other day. Take any old 1N4148 or 1N914 glass-package signal diode and wire it up right, and you’ve got yourself a nifty little IR detector.

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 ...

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 ...
