Electron trapping by neutral pristine ferroelectric domain walls in BiFeO3
Sanvito, Stefano; Körbel, Sabine; Hlinka, Jirka (2018)First-principles calculations for pristine neutral ferroelectric domain walls in BiFeO3 reveal that excess electrons are selectively trapped by the domain walls, while holes are only weakly attracted. Such trapped excess ... -
Interlayer dielectric function of a type-II van der Waals semiconductor: The HfS2/PtS2 heterobilayer
Sanvito, Stefano; Colibaba, Stefana Anais; Körbel, Sabine; Motta, Carlo; El-Mellouhi, Fedwa (American Physical Society (APS), 2019)Heterogeneous stacks of two-dimensional transition-metal dichalcogenides can be arranged so as to have a type-II band alignment, where the valence band maximum and the conduction band minimum are located on different layers. ...
