摘要:
A radiation detector is disclosed, for the detection of radiation (8), with a given spectral sensitivity distribution (9), which has a maximum at a given wavelength λo, comprising a semiconductor body (1) with an active region (5), provided for detector signal generation and for the incident radiation. In one embodiment, the active region (5) comprises a number of functional layers (4a, 4b, 4c, 4d), with differing band gaps and/or thicknesses and embodied such that said layers (4a, 4b, 4c, 4d) at least partly absorb radiation at a wavelength greater than λo. In a further embodiment, a filter layer structure (70) is arranged after the active region, comprising at least one filter layer (7, 7a, 7b, 7c). The filter layer structure determines the short wave side (101) of the detector sensitivity (10), according to the given spectral sensitivity distribution (9), by means of absorption of wavelengths less than λo. A radiation detector for the detection of radiation (8), according to the spectral sensitivity distribution (9) of the human eye is also disclosed. The semiconductor body can be monolithically integrated.
