2D Wannier-Mott exciton binding energy and diamagnetic shift

Hieu T. Nguyen-Truong

Dong Nai Technology University

By approximately solving the Schrödinger equation for two-dimensional (2D) Wannier-Mott excitons with and without magnetic fields, we derive expressions for the exciton energy level and the diamagnetic coefficient. We use the approximate Rytova-Keldysh potential to describe the electron-hole interaction, taking into account environmental effects. Our results [1, 2] agree well with experimental data.
