Pressure evolutions of Tc of metal tellurides with different configurational entropy of mixing. (a) Pressure dependence of \(T_{{\text{c}}}^{{{\text{onset}}}}\) of AgInSnPbBiTe5. Open and filled circles indicate the data taken without a pressure cell, and the data that was measured with DAC. The structural types are indicated according to structural analyses in Fig. 3d. (b) Pressure dependences of \(T_{{\text{c}}}^{{{\text{onset}}}}\) for PbTe, AgPbBiTe3, and AgInSnPbBiTe5. (c) Schematic images of NaCl-type crystal structure and configurational entropy of mixing (ΔSmix) at the M site of PbTe, AgPbBiTe3, and AgInSnPbBiTe5.
