Abstract

Stanene, a two-dimensional nanostructure of Sn atoms, has a honeycomb structure. The strong intrinsic spin-orbit interaction of stanene causes an energy gap 0.07 eV in its band structure. In this research, the electronic properties of the stanene nanoribbons with the zigzag edges are investigated by the tight binding model and the Green’s function method and in the presence of electric and magnetic fields. In the presence of a vertical electric field, we observe metal-semimetal and semimetal-semiconductor phase transitions in the system. In the presence of a transverse electric field and or magnetic field, we will have spin band splitting. Our results show that by tuning the magnitude and direction of the electric and magnetic fields, we can control the electrical, spin and optical properties of the system.
