Aalto University present light detector with record-high sensitivity that may revolutionize imaging

Aalto University has presented a new light detector with record-high sensitivity that may revolutionize imaging. The research team led by Prof. Hele Savin claim that that the new light detector can capture more than 96 % of the incoming photons from visible, ultraviolet through to infrared wavelengths. The key feature is a nanostructured antireflection without limitation to specific wavelengthe or incident angle.
You probably guessed it by now - yes the new detector uses ALD - an inversion layer deposited by ALD.
"We also addressed electrical losses present in traditional sensors that utilize semiconductor pn-junctions for light collection. Our detector does not need any dopants to collect light - instead we use an inversion layer generated by atomic layer deposited thin film."
