Abstract
AlGaAs/GaAs photodetectors operate at room temperature in the visible spectrum. Distinctive features of the photodetectors are: high absolute spectral sensitivity up to 0.112 A / W at μmax = 530–570 nm; photodiodes showed the low dark current of 4.7 nA and 530 nA, accordantly, at 5 V reverse bias. The shift of the spectral characteristics which is associated with an increase in the band gap was detected.
