Abstract
We present experimental study of photoresponse in small area GaAs/AlGaAs heterojunction planar detector induced by nanosecond CO2 laser pulses. This device revealed itself as a fast IR sensor operating at room temperature. Hot carrier effects are proposed to be responsible for the photoresponse formation.
