Electrical Conductivity Behavior of CdHgI4 – CuI Mixed System

Khalid Siraj, Rafiuddin Rafiuddin

Abstract


In this paper the electrical conductivity behaviour in CdHgI4 - CuI mixed system were investigated. The mixed system were prepared by mixing CdHgI4 with CuI in different mol% (10:90, 20:80, 30:70, 40:60 and 50:50 ratios). It was observed that the conductivity of 10:90 CdHgI4 – CuI mixed system were higher than the other system. This increase in conductivity is due to the availability of additional vacancies created by addition of CdHgI4 in CuI, but above 10mol% CdHgI4 the conductivity of mixed system decreased due to the reduction in the mobility of Cu+ ion following vacancy interactions. Activation energy data also suggested the higher conductivity for 10:90 mol% mixed system.
