Soft phonon modes driven reduced thermal conductivity in self-compensated Sn1.03Te with Mn doping

The key challenge for superior thermoelectric performance of SnTe is optimization of very high hole concentration (∼1021 cm−3) arising from inherent Sn vacancies. Partial control of charge carriers can be achieved by self-compensation via careful filling of the vacancies using excess Sn, although hi...
