This effect exists only for low frequency modulation of optical excitation. This phenomenon was explained by the inhomogeneity of potential barriers and surface states density in heteroepitaxial gallium nitride layers caused by their columnar structure.}, title={Surface photocurrent nonuniformities in MSM detectors fabricated in gallium nitride heteroepitaxial layers}, type={artykuł}, contributor={Gaj, Miron.
