Radiation detector working according to preset spectral sensitivity distribution, e.g. typically of human eye, with maximum at preset wavelength, containing semiconductor body

摘要

Radiation (8) detector works according to preset spectal sensitivity distribution with maximum at preset wavelength. It contains semiconductor body (1) with active region (5) for detector signal generation and radiation reception.Active region contains several functional layers (4a-d) with different band gaps and/or thicknesses. They absorb radiation in wavelength range, containing wavelength greater than preset wavelength. Preferably preset spectral sensitivity distribution is that of human eye.
