Tunable electronic structures of germanane/antimonene van der Waals heterostructures using an external electric field and normal strain |
Band structure of (a) pristine germanane, (b) pristine antimonene, and (c) model II of germanane/antimonene vdW heterostructure. (d) Band alignment of germanane/antimonene vdW heterostructure at PBE level. The Fermi level is set at 0 eV and is represented by black dashed line. |
