Exciton−longitudinal-optical phonon coupling in quantum wires and quantum dots

Abstract In this paper, by using the recently proposed theoretical approach for the study of exciton−longitudinal-optical (LO) phonon coupling in semiconductor quantum-well (QW) structures and bulk materials, we have deduced, for the first time, the exciton−LO phonon coupling strength in quantum wire (QWR) and quantum dot (QD) structures, and explained quantitatively the typical experimental results of GaAs/AlAs QWR and CdSSe semiconductor micro-crystallites. The theoretical approach has been shown clearly of being applied to other low dimensional semiconductor materials.
