An analysis of Schottky barrier in silicene/Ga2SeS heterostructures by employing electric field and strain

Two-dimensional materials are leading the way in nanodevice applications thanks to their various advantages. Although two-dimensional materials show promise for many applications, they have certain limitations. In the last decade, the increasing demand for the applications of novel two-dimensional materials has accelerated heterostructure studies in this field. Hence, restoring the combination of two-dimensional heterostructured materials has been reported. In this paper, we show that the effect of the external electric field and biaxial strain on the silicene/Ga2SeS heterostructure has a critical impact on the tuning of the Schottky barrier height. The findings such as the variation of the electronic band gap, interlayer charge transfer, total dipole moment, and n-type/p-type Schottky barrier transitions of the silicene/Ga2SeS heterostructure under external effects imply that the device performance can be adjusted with Janus 2D materials.

Automated summary

Two-dimensional materials have great potential in nanodevice applications but also have limitations. The increasing demand for novel two-dimensional materials has accelerated heterostructure studies. This paper investigates the effects of an external electric field and strain on a silicene/Ga2SeS heterostructure, finding that the device performance can be adjusted by tuning Janus 2D materials.
