Theory of Critical Layer Thickness of Nonconstant Quantum-Well Width Produced by Interdiffusion and its Optoelectronics Consequence
Published online by Cambridge University Press: 10 February 2011
Abstract
In this paper, the concept of critical layer thickness is applied to the interdiffused quantum well (DFQW) structure. For the as-grown InGaAs/LnP lattice matched quantum well, the interdiffusion process will induce in-plane strain into the DFQW forming a lattice mismatched system. The relation between the as-grown well width (Lz) and the diffusion length (Ld) for formation of dislocation is presented.
