High-throughput synthesis of bulk thermoelectric chalcogenides
This study explores the high-throughput synthesis of p-type ternary chalcogenides bismuth antimony telluride Bi2-xSbxTe3 (BST), specifically targeting compositions of Bi0.4Sb1.6Te3, Bi0.5Sb1.4Te3 and Bi0.6Sb1.4Te3. Using the in-house developed 6S, a self-sintered scalable solid-state synthesis techn...
