Spin transport in edge passivated armchair silicene nanoribbons by vanadium
摘要
Abstract
Employing the first-principles simulations combining the density functional theory and the non-equi-librium Green′s function method,we studied spin transport properties of edge passivated armchair silicene nanoribbon(ASiNR)by vanadium atoms. Using transition metal vanadium and halogen fluorine atoms to func-tionalize ASiNR on edge,we designed three kinds of novel crystal structures.Establishing the corresponding two-terminal device systems and simulating the electronic transmission spectrum in different configurations of elec-trode magnetization,we found that spin filtering and giant magnetoresistance effects appear in all of them. In ad-dition, significant spin Seebeck effects are realized in one of the systems with antiferromagnetic configuration in the temperature range between-223 and-123 ℃.关键词
