عنوان مقاله [English]
In this paper, the electronic properties and topological phase of Li2AgSn nanolayer are investigated. The calculation is done based on the density functional theory within generalized gradient approximation (GGA) using full potential Linearized Augmented Plane Waves plus local orbitals . The electron density of states of this nanolayer is calculated using GGA approximation. The linear electron specific heat coefficient of Li2AgSn nanolayer is calculated. The xx and zz compounds of dielectric constant, reflection, absorption, refraction, extinction coefficients and energy loss function of this nanolayer are investigated. The topological phase and band order of this nanolayer are investigated by using the band structure.
