- Summary:Inspired by stable two-dimensional antimonene phases, two new allotropes (S/O and tricycle) antimonenes
have been predicted by first-principles calculations in this paper. S/O type antimonene possesses
remarkably thermodynamical and dynamical stability, which are comparable to that of buckled type
antimonene. The results indicate that S/O type antimonene is a direct band gap semiconductor with a
band gap of 2.314 eV and the electronic properties could be effectively tuned by the in-plane strain. In
order to explore the potential application, the mechanical properties and optical properties of S/O type
antimonene are also extensively studied. It is found the S/O type antimonene is an anisotropic material
by the method of analyzing the linear Poisson’s ratios and the phonon band structure. These systematical
analyses show that S/O type antimonene is a new 2D material with tunable electronic properties, excellent
mechanical and optical properties. - Co-author:T.T. Li , C. He*, W.X. Zhang
