This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

Scientists have revealed how microscopic defects trigger catastrophic failure in perovskite solar cells. A research ...

Researchers at the University of Colorado Boulder and NREL have uncovered the reason, microscopic defects that turn into heat-trapping hotspots, threatening to short-circuit the next generation of ...

For our 2025 Component Abuse Challenge there have been a set of entries which merely use a component for a purpose it wasn’t quite intended, and another which push misuse of a part into ...

With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.

For the Component Abuse Challenge our hacker [Tim Williams] observes that N-P-N reads the same way forwards and backwards, so ...

Abstract: The reliability of the low-barrier Poly-Si/4H-SiC heterojunction is experimentally demonstrated for the first time, with a superior long-term forward conduction and reverse blocking ...

Abstract: GaN-based heterostructures are typically grown in the polar direction. Due to differences in polarization constants between layers of varying composition and the built-in strain, significant ...
