An UV detector based on nanocrystals synthesized by using ion implantation

09-Aug-2018

Scientists at the Lobachevsky University have been working for several years to develop solar-blind photodetectors operating in the UV spectral band. In the field of electronic technology, this is an important task, since such devices cut off emission with a wavelength higher than 280 nm, which ...
