Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

Abstract: A novel technique to tailor the carrier lifetime in silicon diodes by combining electron irradiation and hydrogen implantation is presented. The electron defects are locally passivated by ...

Researchers optimise ultraviolet avalanche photodiodes by fine-tuning electric field and absorption layers, increasing ...

Abstract: This paper proposes and experimentally validates a hyper-hemispherical high-resistivity silicon lens-coupled high-electron-mobility transistor (HEMT) detector integrated with an off-axis ...

OPSWAT’s Jan Miller explains how the threat landscape is changing, why legacy defences are failing and what businesses must ...
