Theoretical insight into structure stability, elastic property and carrier mobility of monolayer arsenene under biaxial strains

Through theoretical calculations, we investigate the structure stability, elastic property and carrier mobility of Arsenene. Using phonon spectra and elastic constant, we verify the dynamic stability and mechanical stability of Arsenene. Based on the stable structure, we study the elastic property and carrier mobility. The bulk modulus, shear modulus, Young's modulus, Poisson's ratio are calculated. Finally, the Shear anisotropy, Vicker hardness, Debye temperature, melting point and thermal conductivity have been predicted. According to deformation potential theory, under different strain and temperature, the electron mobility and relaxation time are also calculated. (C) 2016 Elsevier Ltd. All rights reserved.
