Experimental heat capacity of LiInS.sub.2, LiInSe.sub.2, LiGaS.sub.2, LiGaSe.sub.2, and LiGaTe.sub.2 from 180 to 460 K

Heat capacity of single-crystal samples of five chalcogenides (LiInS.sub.2, LiInSe.sub.2, LiGaS.sub.2, LiGaSe.sub.2, and LiGaTe.sub.2) was measured with DSC in a temperature range from 180 to 460 K. The data for LiInS.sub.2 and LiInSe.sub.2 were compared with the literature data and shown to agree w...

Description
Summary:Heat capacity of single-crystal samples of five chalcogenides (LiInS.sub.2, LiInSe.sub.2, LiGaS.sub.2, LiGaSe.sub.2, and LiGaTe.sub.2) was measured with DSC in a temperature range from 180 to 460 K. The data for LiInS.sub.2 and LiInSe.sub.2 were compared with the literature data and shown to agree with the results of adiabatic calorimetry (Gmelin and Hönle in Thermochimica Acta 269: 575-590, 1995 (See CR7)) better than with other DSC data (Kühn et al. in Cryst Res Technol 22: 265-269, 1987 (See CR5)). Besides, the high-temperature fitting polynomial for C.sub.P(T) published about 30 years ago for LiInS.sub.2 is wrong. LiGaS.sub.2, LiGaSe.sub.2, and LiGaTe.sub.2 were measured for the first time.
