a Total thermal conductivity (κT), b lattice thermal conductivity (κL), c comparison of κL, d calculated lattice thermal conductivities of SnSe compounds based on the Callaway’s model. The black, red, green, orange, and blue lines represent the lattice thermal conductivities of pristine SnSe, VSe (with 8% Se vacancy in SnSe), VSn (with 14% Sn vacancy in SnSe), VSn + VSe (with 8% Se and 14% Sn vacancies in SnSe) and 3%WCl6 + VSn + VSe (with 8% Se and 14% Sn vacancies plus 3% WCl6 doping in SnSe), respectively.
