We calculated the electronic structure and optical properties of the AlN monolayer based on first principle many-body Green’s function and Bethe–Salpeter equation formalism. We computed that

the indirect (direct) ...

Usingfirst principles many-body theory methods (Green s function and Bethe Salpeter equation

formalism) we calculated the electronic structure and optical properties of the GaAs monolayer. We

computed that ...

First principle calculations based on density functional theory using GW approximation and two particle Bethe–Salpeter equation with electron-hole effect were performed to investigate electronic structure and optical ...
