Abstract
The thermal expansion and isothermal compressibility of TlGaS2 were measured between 77 K and room temperature. No anomalies in the temperature dependences of these properties were detected. The experimental data were used to evaluate the Debye temperature, rms dynamic atomic displacements, the difference between the specific heats at constant pressure and constant volume (C p – C V), and the Grüneisen parameter. The appreciable discrepancy between the C p – C V values calculated using thermodynamic relations and an empirical formula is attributed to the pronounced anisotropy of TlGaS2.
