Strain Profiles and Electronic Structure of a Self-Assembled Quantum Ring
Media Details
Created 03/15/2011
This compound image illustrates a theoretical investigation of the strain profiles and electronic structure of a self-assembled quantum ring. The authors report anomalous strain relaxation and an enhancement of the light-hole character due to the GaAs layer on the InAs/InGaAs quantum ring. The analysis of the band structure of the strained InGaAs compound explains the half-well and half-barrier character of the strained GaAs layer embedded in the InP matrix.
