Abstract

We have measured the contactless electroreflectance and piezoreflectance spectra at 300 and 20 K from a GaN/AlGaN heterojunction structure grown by metalorganic chemical vapor deposition on 6H-SiC substrate. The features related to a two-dimensional electron gas confined at the GaN/ AlGaN heterojunction are observed and the origin and nature of these features are discussed.
