Anisotropic exciton excitations and optical properties of Hittorf's phosphorene
Ju Zhou, Tianyi Cai, Sheng Ju
Abstract
This paper presents a first-principles approach to the quasiparticle electronic structure, exciton, and optical properties in two dimensional Hittorf's phosphorene. The authors show the onset of exciton-enhanced optical absorption and strong polarization-dependent electron-hole excitation.
