Numerical Study of Bandgap Renormalization in V-Grooved Quantum Nanowires

Nozari, K; Madadi, Mahyar; Narimani, N

Description

By considering a suitable confinement potential, we calculate the exchange-correlation induced band gap renormalization (BGR) in a V-grooved quantum wire as a function of the electron-hole plasma density and quantum wire width. The leading-order GW dynamical screening approximation is used in the calculation by treating the electron-electron Coulomb interaction and electron-optical phonon interaction. A numerical scheme has been proposed, and the screened Coulomb potential, density of states...[Show more]
