Abstract
Provided is a method of preparing an SnSe thermoelectric material including (a) heating a mixture including Sn2+ and Se2−, (b) cooling the mixture at a cooling rate greater than 0 and equal to or less than 3 K/h, and forming single crystal Sn1−xSe (where 0<x<1), and an SnSe thermoelectric material prepared thereby and including Sn vacancies.
Claims7
