Embodiments of a method of quantum well intermixing (QWI) comprise providing a wafer comprising upper and lower epitaxial layers, which each include barrier layers, and a quantum well layer disposed between the upper and lower epitaxial layers, applying at least one sacrificial layer over the upper epitaxial layer, and forming a QWI enhanced region and a QWI suppressed region by applying a QWI Cited by: A simpler and more cost-effective approach for bandgap tuning is the post-growth quantum well intermixing (QWI). Over the years different QWI techniques have been developed, such as impurity-induced disordering (IID) , , photoabsorption-induced disordering (PAID)  and impurity-free vacancy disordering (IFVD) , .
Abstract. In this contribution, we review some basic optical properties of semiconductor quantum wells. Emphasize is brought on the experimental point of view, since another chapter of the present volume  adresses the theoretical conterpart.

Keywords: Quantum well, Semiconductor, Heterostructures, Lasers, Detectors, Modulators. 1. Introduction Quantum well (QW) devices are devices that use quantum well effects. The basic concept of a quantum well is illustrated in Fig The basis of a quantum well device is a situation where a thin semiconductor layer of lower. “I think it is safe to say that no one understands quantum mechanics.” —Physicist Richard P. Feynman To say that the invention of semiconductor devices was a revolution would not be an exaggeration. Not only was this an impressive technological accomplishment, but it paved the way for developments that would indelibly alter modern society.

The structure is subsequently annealed to promote quantum Cited by: Diffusion or intermixing is the movement of particles through space. It primarily occurs in every form of matter because of thermal motion.
Atom diffusion and intermixing can also happen in crystalline semiconductors whereby the atoms that are diffusing and intermixing move from one side of the lattice to the adjacent one in the crystal semiconductor.
