Моделирование фотоэлектронных спектров монослоя сурьмы

Abstract

Based on the minimal tight-binding model, angle-resolved photoemission spectra of the antimony monolayer was simulated in terms of dynamical mean-field theory. The dynamical Coulomb correlations were found to strongly affect the energy gap. It reveals electron-electron interplays to be essential to describe the experimentally available properties of the system.
