Abstract
SnTe has drawn much attention due to its Pb-free composition along with tunable electronic and lattice structures. However, its intrinsically high defect concentration and high lattice thermal conductivity ( κ1) have hindered its application in devices. Recently, Bi doping at Sn-sites in Sn 1-xBi xTe ( x = 0.0 – 0.08) has been demonstrated..... More
