摘要：
It is shown that optical reflectance spectra of Al0.1Ga0.9N thin films deposited on sapphire substrates exhibit some special features in the range of 4.0-5.5 eV, which is confirmed by modulation and photosensitivity spectra. These special features can be explained taking into account the biaxial strain when calculating the dielectric function in the pseudopotential approximation. (C) 2002 MAIK "Nauka / Interperiodica".
