We review how the tight-binding method provides a particularly useful approach to understand the electronic structure of GaInNAs alloys, and use it to derive a modified k?p model for the electronic structure of GaInNAs heterostructures. Using the tig

The pressure and temperature dependence of quantum well transitions in GaNxAs1—x/GaAs quantum well structures with xN = 1.8% and various well widths grown by metal organic vapour phase epitaxy were studied by photomodulated reflectance (PR) spectro

We report photo-modulated reflectance studies under applied pressure and variable temperature, and related calculations, that probe the influence of N-related resonant anti-bonding states on the electronic structure of dilute III–N–V quantum well

Landau-level lifetimes are determined from saturation cyclotron resonance (CR) in wide parabolic wells, quantum wells and bulk PbTe-Pb1-xEuxTe systems. These narrow gap structures exhibit strong band non-parabolicity necessary to terminate the normal

We have studied the effects of a tilted magnetic field on the magneto-photoluminescence intensities in a GaAs/GaAlAs modulation doped single quantum well. For small tilt angles, the parallel component of the magnetic field induces an increase of the

We report pressure dependent photomodulated reflectance (PR) measurements on a series of dilute-N InGaNAs/GaAs multiple quantum wells (MQWs). Our experimental results indicate the presence of important N-related disorder effects due to different near
