Original Abstract

Flicker noise of CdTe radiation detectors was measured and analyzed. Two CdTe detectors were used for the measurements. Both detectors have p-type conductivity. One of them has low-ohmic contacts (F33B8), another one have high-ohmic contact (452D). The value of flicker noise for both detectors was much higher than theoretical value for CdTe single crystals. It was suggested that the contact area was the source of extra high low frequency noise value. This paper shows the analysis of this possibility
