Topological insulators have been considered as promising thermoelectric materials because of their high electrical transport properties and low thermal conductivity. In this work, the crystal structure, chemical composition, and thermoelectric transport properties of a weak topological insulator, Bi2TeI, were studied. Bi2TeI possesses the lowest lattice thermal conductivity compared with the analogously layered compounds Bi2Te3 and BiTeI. Cu and Zn were used as dopants with the aim of… CONTINUE READING
