The attractive mechanical and electronic properties of freestanding graphene has led to the exploration of two-dimensional (2D) materials which can be integrated with contemporary electronics. As a 2D analog of graphene, stanene has become a hopeful candidate for 2D films due to its excellent quantum effects, superconductivity, and thermoelectric properties. Focusing on the promising 2D elemental material stanene, the fundamental electronic properties and experimental preparation of this material are reviewed. The prospects of utilizing the ability to manipulate the electronic properties of stanene for nanoelectronic and optoelectronic applications are determined.
Thermoelectric properties of a quantum dot (QD) connected to two metal leads are studied, where the QD is fabricated by the quantum anomalous Hall insulator. Surface states emerge at the edge of the QD due to the bulk‐boundary correspondence, while bulk states spread over the whole QD. Fano interference will occur between tunneling via surface and bulk states, which leads to asymmetric lineshape and minimum in the transmission and electric conductance spectrums. Both Seebeck coefficient and thermoelectric figure of merit are enhanced greatly in the energy regime of Fano interference. In addition, it is shown that Fano interference and thermoelectric properties can be well tuned by magnetic field.
