Magnetic Quantization of SnTe Slabs with Various Orientations and Terminations

ORAL

Abstract

We investigate the electronic band structures and magnetic quantization of SnTe slabs with (100), (110), and (111) orientations by using a tight-binding model. For each orientation, we examine how different surface terminations (Sn- or Te-terminated) modify the electronic structure relative to the bulk. The reduced dimensionality and broken mirror and inversion symmetries lead to remarkable energy shifts and hybridization-induced splittings of the surface-state bands. Under a perpendicular magnetic field, the resulting Landau level spectra exhibit orientation- and termination-dependent features that reflect these symmetry-breaking effects.
