Recent progress in the study of stanene
Inspired by the successfully experimental realization of graphene, other ultrathin materials consisting of group IV elements Si, Ge and Sn have been attracted plenty of interests due to their unprecedented electronic properties. Among them, two dimensional low buckled Sn based stanene and its derivatives present novel quantum properties due to its large spin orbital coupling, such as a quantum spin Hall insulating behaviour with a very large band gap, and the capability to support enhanced thermoelectric performance, topological superconductivity and the near room temperature quantum anomalous Hall effect and so on. Therefore, stanene shows the great application potentials in the dissipationless electric conduction at room temperature, high performance thermoelectricity, spintronics and topological quantum computation. This review will briefly introduce the recent progress in the study of stanene both in theory and in experiment.
