Abstract

Multilayered samples with extremely narrow GaN quantum wells in an AlN host are synthesized via ammonia MBE. The parameters of the microstructu re are determined by means of EXAFS spectroscopy, high-resolution electron microscopy, and low-angle sc attering. Their relationship to the morphology of GaN/AlN superlattices is established. The influence of growth conditions and the thickness of superlattices on their optical properties and mixing in the near-boundary layers is established.
