Entropy-driven structural transition from Tetragonal to Cubic phase: High Thermoelectric Performance of CuCdInSe3 compound

High-entropy materials for thermoelectric applications: towards performance and reliability

“…Luo et al 242 found that the order–disorder transition driven by entropy at the cation site, coupled with increased phonon scattering due to CdSe alloying in CuInSe 2 , significantly suppresses k , leading to an improved ZT of 0.45 at 780 K for CuCd 1.005 InSe 3 . Wang et al 243 successfully synthesized Sn 1−2 x (AgBi) x Se samples using vacuum melting and SPS.…”
