Aa. Kopylov et al., INFRARED REFLECTION AND OPTICAL PHONONS IN EPITAXIAL LAYERS OF THE SOLID-SOLUTIONS INXGA1-XAS GAAS/, Semiconductors, 30(5), 1996, pp. 485-486
Infrared reflection from InxGa1-xAs/GaAs (x = 0.12-0.26) layers in the
region of the spectrum 100-400 cm(-1) is investigated. The reflection
spectra are analyzed for the model ''epitaxial layer - semi-infinite
substrate'' using the standard multioscillator dielectric function. Th
e phonon frequencies are discussed in connection with the possible ord
ering of the crystal lattice of the solid solution. (C) 1996 American
