First-principles many-body comparative study of Bi2Se3 crystal: A promising candidate for broadband photodetector
In this work, we present a theoretical investigation on the structural, electronic and optical properties of Bi2Se3 via density functional theory (DFT) approach in conjunction with a many-body perturbation theory (MBPT) formalism. It was found that inclusion of van der Waals (vdW) correction reprodu...
