Paper Abstract
We report the results of a study of photovoltage which is generated on p-n and l-h GaAs structures under pulsed infrared laser excitation. The hot carrier photocurrent reaches its maximum value at bias voltage related to potential barrier height of p-n junction. We demonstrate that the photoresponse consists of fast and slow components which result from free-carrier and crystal lattice heating, respectively. The obtained results indicate that nonuniform GaAs structures can be used for fabrication of fast detectors based on free-carrier heating by infrared light.
