Abstract : Hall effect and conductivity measurement are carried out on chlorine doped semi-insulating CdTe crystals, of p and n electric type. In p type crystals the depth of the dominating level is determined ≃ Ev + 0.7 eV as well as the concentration of associated centres 1013-1014 cm -3. The mobility values are limited by a process of diffusion on heterogeneities.

Keywords : cadmium compounds chlorine deep impurities electrical conductivity of crystalline semiconductors and insulators II VI semiconductors Hall effect conductivity deep levels semiinsulating CdTe:Cl II VI semiconductor p type n type associated centre concentration carrier mobility
