Abstract

Room-temperature Raman spectra were measured for CuAlSe2 heteroepitaxial layers grown on GaAs (001) and GaP (001) substrates. A remarkable difference in the polarized Raman spectra was noted, and the results were attributed to be due to the lattice orientation of the epilayers on the basis of the polarization selection rules of Raman active modes. Two vibrational modes were assigned, namely the A1 mode at 189 cm-1 and longitudinal-optical B2 mode at 89 cm-1.
