Low-temperature heat capacity of ZnGa2S4, ZnGa2Se4, and ZnGa2Te4 thiogallates
Description
The results are given of heat-capacity measurements conducted in the temperature range from 5 to 60 K on ZnGa2S4, ZnGa2Se4, and ZnGa2Te4 representing the thiogallate group of A/sup II/B/sup III/2C/sup VI/4-type compounds. On the basis of C/sub p/ (T) data the temperature dependences of the characteristic Debye temperatures THETA/sub D/ (T) were calculated. The existence of a sloping minimum in the THETA/sub D/ (T) dependence is typical of high-symmetry crystals. Extrapolation of THETA/sub D/ (T) to T → 0 has produced THETA0 = (312 +- 6) K, THETA0 = (228 +- 4) K, and THETA0 = (203 +- 3) K for ZnGa2S4, ZnGa2Se4, and ZnGa2Te4, respectively
