Journal ArticleDOI
Tuning the Schottky contacts at the graphene/WS2 interface by electric field
TL;DR: In this article, an external electric field (Eext) perpendicular to the heterobilayers is applied to tune the Schottky contacts, which can transform the n-type into p-type and ohmic contact.
Journal ArticleDOI
Tuning the Schottky barrier in the arsenene/graphene van der Waals heterostructures by electric field
TL;DR: In this paper, the authors investigated the electronic properties of arsenene/graphene van der Waals (vdW) heterostructures by applying external electric field perpendicular to the layers.
Journal ArticleDOI
Band structure engineering in a MoS2/PbI2 van der Waals heterostructure via an external electric field
Yaqiang Ma,Xu Zhao,Tianxing Wang,Wei Li,Xiaolong Wang,Xiaolong Wang,Shanshan Chang,Yi Li,Mingyu Zhao,Xianqi Dai +9 more
TL;DR: It is demonstrated that the MoS2/PbI2 vdW heterostructure has a type-II heterojunction with a direct bandgap, and thus the lowest energy electron-hole pairs are spatially separated.
Journal ArticleDOI
Bandstructure modulation of two-dimensional WSe2 by electric field
TL;DR: By means of density functional theory computations, the authors studied band-gap tuning in multi-layer WSe2 sheets by external electric fields and showed that the fundamental band gap continuously decreases with an increasing vertical electric field, eventually rendering them metallic.
Journal ArticleDOI
Effects of electric field on the electronic structures of MoS2/arsenene van der Waals heterostructure
TL;DR: In this article, a density functional theory (DFT) based approach was proposed to investigate the electronic structures modulation in MoS 2 /arsenene van der Waals (vdW) heterostructure with an external electric field (E ext ).
