摘要：
A pulse method was used to measure the thermal conductivity, specific heat capacity Cp and thermal diffusivityξ of polycrystalline ZnIn2Se4 in the temperature range 300–600 K. The temperature dependence of λ, Cp and ξ demonstrated a light decrease for this material in the temperature range 300–600 K, indicating that there is not a significant change in the structure in this temperature range; this was confirmed by DTA measurements. The results showed that the mechanism of heat transfer is due mainly to phonons; the contributions of electrons and dipoles are very small.
