Güven, K.Tanatar, Bilal2016-02-082016-02-0819950163-1829http://hdl.handle.net/11693/25898We study the effects of screening on polaronic corrections to the effective band edge in a quasi-one-dimensional GaAs quantum wire. We find that the screening effects and finite well width considerably reduce the polaron energy and oppose the polaronic band-gap renormalization. We calculate the polaronic effective mass as a function of the carrier density and temperature. Effects of the vertex corrections to the conduction- and valence-band edges are also discussed. © 1995 The American Physical Society.EnglishArticle10.1103/PhysRevB.51.1784
