Cover

Graphene based all-carbon nano-junction is structurally stable and mechanically flexible. It has been extensively recognized as a good candidate of nanoscale electronic andspin-electronic device. Jian-Wei Li et al. investigated the electronicand thermal electronic transport properties of kinds of graphene basedall-carbon nano-junctions using first principles method. Huge TMR roughly equal to 105 was found for these structures. In addition, thermally induced spin up current and spin down current flow along opposite direction in these systems, which indicates a thermally induced pure spin currents can be obtained in these structures. For more details, please refer to the article “Spin-resolved quantum transport in graphene-based nano junctions” by Jian-Wei Li, et al., Front. Phys.12(4), 126501 (2017).
