Abstract :Specific heat capacity Cp anomalies of layered single crystals TlInS2 and TlGaS2 have been investigated using differential scanning calorimetry (DSC) as a new technique for such crystals. Special features of Cp have been revealed in the temperature range of the possible phase transitions of both crystals. A sequence of maximum values of Cp is obtained at 163, 174, 184, 193, 201, 212, 224, 254, and 259 K for TlInS2. In the case of TlGaS2, the temperatures of the obtained maximum Cp values at 177 and 241 K agree well with the intervals of the phase transition temperatures reported in the published data of TlGaS2. As a result, it is remarked that DSC technique might have a particular potential for the thermal measurements of layered semiconductors.Keywords : Ternary compounds, layered crystal, heat capacity, DSC, phase transition
