Abstract
Bi₂Te₃ shows high thermoelectric performance near room temperature, making it the most widely used material in thermoelectric cooling applications. Cu doping has been found to be effective in improving the thermoelectric performance of Bi₂Te₃. However, due to the problem of easy migration of Cu ions, the stability of Cu-doped Bi₂Te₃..... More

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
