## Abstract Spectroscopic studies have been carried out on the quantum levels in GaInNAs/GaAs single quantum wells (SQWs). Photoluminescence (PL), PL excitation (PLE), photoreflectance (PR), and highβdensityβexcited PL (HDEβPL) were measured on high quality GaInNAs SQWs, Ga~0.65~In~0.35~N~0.01~As~0
We have investigated mesoscopic conductance fluctuations in a GaAs quantum well with five electrically quantised two-dimensional (2D) subbands occupied. The conductance fluctuations occur even in a magnetic field p~rallei to the plane. We attribute the fluctuations to rapid electron-impurity scatter
