Evaluation of the elastic and plastic properties of the antimonene at the presence of the external electric field: a DFT investigation

Abstract

In this paper, the influence of the external electric field on the mechanical properties of the antimonene is investigated. For this purpose, the density functional theory is utilized. Using the uniaxial and biaxial loading, the in-plane Young’s modulus, bulk modulus and Yield’s strain of the antimonene are computed. Also, the variation of an individual bond under the mentioned loading conditions is studied. It is shown that while the in-plane Young’s modulus and bulk modulus of the antimonene are not affected significantly at the presence of the external electric field, the Yield strain after which the nanosheet enters the plastic region significantly decreases noticeably. Besides, the largest tolerated strain by individual bonds is not influenced by the external electric field. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
