Abstract
- The heat capacity of InSe has been measured at temperatures from 11.14 to 325.26 K using an adiabatic calorimeter. The results differ significantly from earlier data (by ∼2.2% at 200 K). The smoothed heat capacity data have been used to evaluate temperature-dependent thermodynamic functions (entropy, enthalpy increment, and reduced Gibbs energy) of indium selenide. Its thermodynamic properties under standard conditions are C (198.15 K) = 49.43 ± 0.10 J/(K mol), S 0(298.15 K) = 82.20 ± 0.16 J/(K mol), H 0(298.15 K) − H0(0) = 10.94 ± 0.02 kJ/mol, and Φ0(298.15 K) = 45.50 ± 0.09 J/(K mol). The Debye characteristic temperature of InSe evaluated from the heat capacity data is 275 ± 15 K. [ABSTRACT FROM AUTHOR]
