Abstract
Low and high electric field transport in the CdIn2Te4 electro-optical semiconductor were investigated. The conductivity, the carrier concentration, and the mobility were measured versus the temperature using Hall techniques. Nonlinear current-voltage characteristics in high fields are interpreted in terms of thermal effects, not in terms of space-charge-limited currents as usually encountered. The nonreversibility of I-V measurements is also discussed, diffusion of species are proposed to explain the change of activation energy of the conductivity.
