Narrow-gap semiconductor solid solutions ZnCdHgTe are of particular interest as an alternative to worldwide known compound CdHgTe. The abstract presents some experimental results on structural and electric field-induced properties of the compound.

The samples were grown on insulator substrates by the pulse laser deposition technology. X-ray diffraction analysis showed a good quality of the deposited films. Transmission line method was applied to measure the surface resistance of the grown layers. Transmission line method gives the value of contact resistance 3 10⁴ Ohm, the surface resistance is 2,5 ^.10⁵ Ohm, the value of contact line l_c = 2.5 mm. Ni contacts are performed by physical vapor deposition technique.

Electric field-induced properties were investigated for as-grown films (at the room temperature and under the applied bias from 0 to 1.0 V) and for the samples underwent a heat treatment in hydrogen during 1 h at T = 300 K. In the first case experimental current-voltage characteristics revealed space-charge-limited currents under all range of applied voltage. In the second case the current-voltage dependencies were changed. Some parameters of the investigated structures as a whole as well as that for the films are calculated. The nature of this behavior is also discussed.
