Paper Abstract

In the paper, a thin tensile GaAs interlayer was used to get regular arrangement of InAs quantum dots (QDs) on InP substrate by LP-MOCVD. Photoluminescence (PL) spectrum, atomic force microscopy (AFM) image and Raman spectrum have been investigated. The five band k(DOT)p formalism in the PL spectrum and frequency shift in Raman spectrum have been performed. The theoretical calculations coincide with our experiment results well. The density of InAs quantum dots at 4 ML InAs is the maximum (1.6X1010cmMIN2).
