Cardiff researchers create low noise compound avalanche diode

Cardiff University researchers from the Institute for Compound Semiconductors (ICS) worked with collaborators to innovate an ultrafast and highly sensitive ‘avalanche photodiode’ (APD) that creates less electronic ‘noise’ than its silicon rivals. APDs are highly sensitive semiconductor devices that exploit the ‘photoelectric effect’ – when light hits a material – to convert light to electricity. Faster, ...
