Abstract :
Transport characteristics of CdTe radiation detectors have been studied. Our aim is study of the charge carrier concentration and their mobility changing in the bulk with temperature. We found that the conductivity of the sample and the bulk conductivity increases very slowly after an external electric field is applied. Each sample shows very high value of relaxation time (hundreds and thousands of seconds).
