Rydberg exciton
In semiconductors, the dielectric constant is generally large. Consequently, electric field screening tends to reduce the Coulomb interaction between electrons and holes. The result is a Wannier–Mott exciton, which has a radius larger than the lattice spacing. Small effective mass of electrons that is typical of semiconductors also favors large exciton radii. As a result, the effect of the lattice potential can be incorporated into the effective masses of the electron and hole. Like… WebJun 29, 2024 · The term, Rydberg exciton, refers to a larger exciton where an electron sits in a higher-energy state and, thus, its circulating orbit is farther from the centre of a hole with …

WebWe have identified excited exciton states in monolayers of MoS 2 and WS 2 supported on fused silica by means of photoluminescence excitation spectroscopy. In monolayer WS 2, the positions of the excited A exciton states imply an exciton binding energy of 0.32 eV. Webthe strong confinement limit, the picture of an exciton would be destroyed, as one would then treat electron and hole separately with their individual motions being quantized. In this case, the confinement energy dominates over the Rydberg exciton binding energy. 2. Methods In order to calculate the energy shifts a Rydberg exciton
