The results of the investigation of the galvanomagnetic properties of thin layers of solid solutions of Cd1-XZnXTe are given. The activation energy of acceptors equals to 0.22 eV for a layer with x = 0.2 and to 0.38 eV for a layer with x = 0.4 were calculated. In the n-CdTe-p-Cd0.8Zn0.2Te heterostructures the direct currents exceed the inverse currents by a factor of ~ 105. The main mechanism of current flow through the barrier is over-barrier diffusion.
