摘要: Transport and thermoelectric coefficients (including also spin thermopower) of silicene nanoribbons with zigzag edges are investigated by ab initio numerical methods. Local density such reveals edge magnetism. As in graphene, one finds antiferromagnetic ferromagnetic ordering, polarization at antiparallel or parallel to that the other edge, respectively. Thermoelectric properties, especially Seebeck coefficient, significantly depend on electronic band structure enhanced when Fermi level is energy gap. However, efficiency reduced phonon contribution heat conductance included. This has been calculated numerically two different Transition from states leads a large magnetoresistance as well considerable magnetothermopower. parameters configuration, left part nanoribbon opposite right part, analyzed.
