Facile Synthesis and Enhancement of Thermoelectric Performance with Voltage Generation of Bulk Polycrystalline SnSe by Zn Doping

“…The deconvolution of the Sn 3d 5/2 peak (Figure a) of green and 200 °C sintered SnSe indicates the presence of SnO 2 , SnSe 1+ x , and SnSe at their corresponding binding energies (BEs), i.e., 487.54, 486.96, and 486.22 eV, respectively, whereas the BEs at 487.56 and 486.18 eV in 600 °C sintered SnSe belong to SnO 2 and SnSe. The BEs at 486.5 and 485.7 eV in Zn (0.03 and 0.05)-doped SnSe belong to the SnO 2 and SnSe phases . A slight shift toward the lower BE in the Sn 3d 5/2 orbital in Zn-doped pellets shows the substitution of Sn by Zn atoms.…”

“…Further investigations were conducted to confirm the presence of secondary phases, which are discussed below. 43 A slight shift toward the lower BE in the Sn 3d 5/2 orbital in Zndoped pellets shows the substitution of Sn by Zn atoms. The shift in the peak was caused by a change in bond length between Sn and Se after Zn doping, which resulted in a change in the equilibrium of nuclear geometry between the system's ground state and final ionized state.…”
