THE INFLUENCE OF γ-IRRADIATION ON ELECTRICAL PROPERTIES OF CdIn2Te4 CRYSTALS
RESUMO
The influence of γ-irradiation on the basic electrical parameters of CdIn2Te4 crystals in the temperature range of 240-410 K has been investigated. It was established that the noticeable changes in the parameters of the irradiated samples take place under irradiation doses D > 1·108 Roentgen. It was shown that under dose D = 1.2·108 Roentgen and additional dose D = 4·108 Roentgen the parameters change slightly at high temperature T > 350 K and at T < 350 K the changes of parameters increase with rising γ-irradiation dose. The anomalous increase of the Hall mobility in the irradiated samples was found and the explanation of the obtained effect nature was proposed. It was shown that the main cause of the changes of the electrical parameters under the influence of γ-irradiation is the Fermi-level displacement within the energy gap of CdIn2Te4 crystals.
