Description:
Author(s): Congxin Xia, Juan Du, Meng Li, Xueping Li, Xu Zhao, Tianxing Wang, and Jingbo Li Custom-made stacks of two-dimensional materials can be constructed to achieve specific optoelectronic properties in devices. This work uses density functional theory to investigate the electronic structures and transport properties of phosphorene–tin-dichalcogenide van der Waals heterostructures in an external electric field. The results show that these systems exhibit rare type-III (broken-gap) band alignment, which will facilitate the development of tunnel field-effect transistors. Moreover, the band alignment can be tuned effectively by the applied electric field. [Phys. Rev. Applied 10, 054064] Published Wed Nov 28, 2018
