Abstract
We report on a study of the optical properties of undoped AlN/GaN superlattices by means of spectroscopic ellipsometry and photo- and cathodoluminescence. The effect of well and barrier thicknesses on the superlattice transition energies has been studied. Model calculations of the SL miniband structure are performed to compare theoretical predictions with the experimentally determined values of the transition energies.
