It is shown that, in spite of the linearity of current-voltage characteristics of ionizing-radiation detectors based on semi-insulating GaAs compensated with Cr, the charge transport in these detectors is controlled by the barrier contacts at the ano

Unlike conventional GaAs detector structures that use a space charge region (SCR) of a barrier structure, we propose to form a detector structure of resistor type made of GaAs compensated with Cr. In this case, the electric field distribution, ξ(x),
