Preferred Label : photoconductive detector;
IUPAC definition : In a photoconductive detector an electric potential is applied across the absorbing
region and causes a current to flow in proportion to the irradiance if the photon
energy exceeds the energy gap between the valence and the conduction band. Depending
on their spectral responsivity function, photoconductive detectors are divided into
photoconductive detectors for the visible wavelength range e.g. cadmium sulfide or
CdS photoconductive detectors, photoconductive detectors for the near infrared wavelength
range e.g. lead sulfide or PbS photoconductive detectors, photoconductive detectors
for the infrared wavelength range e.g. silicon doped with arsenide or Si:As photoconductive
detectors, and the mercury-cadmium-telluride or HgCdTe photoconductive detector.;
