Tin selenide might considerably exceed the efficiency of current record holding thermoelectric materials made of bismuth telluride. However, it was thought its efficiency increased dramatically only at temperatures above 500 degrees Celsius. Now measurements at the BESSY II and PETRA IV synchrotron sources show that tin selenide can also be utilised as a thermoelectric material at room temperature—so long as high pressure is applied.
