Originální abstrakt

This paper presents the results of experimental studies of transport and noise characteristics of CdTe deterctors. The current – voltage (I-V) characteristics and noise spectral densities were measured at the room temperature in dark and illumination through the contact area. We found that in this sample are good ohmic contacts and then measured noise corresponds volume noise sources only. The dominant noise source is 1/f type. One sample met the criteria to assumed bz the Hooge model. The Hooge constant for this sample was found: 5.5x10^-2. This value is higher than 2x10^-3 proposed by the Hooge theory due to the contact noise sources. Nevertheless, this value is very close to the theoretical.
