Spin-dependent thermoelectric effects in Fe-C6 doped monolayer MoS2

Spin-dependent thermoelectric effects in Fe-C6 doped monolayer MoS2

Abstract By using the non-equilibrium Green’s function with density functional theory, we have studied the thermal spin transport properties of Fe-C6 cluster doped monolayer MoS2. The results show that the device has a perfect Seebeck effect under temperature difference without gate voltage or bias...
