Abstract

Vibrational spectra of gas-source molecular beam epitaxy grown dilute InN_xAs_1-x/InP (001) alloys are obtained using a Fourier-transform infrared (IR) spectroscopy. A triply degenerate N_As local vibrational mode of T_d-symmetry is observed near 438 cm ^-1 corresponding to the In-N bond energy. The analysis of composition dependent infrared reflectivity spectra in InNAs has predicted a two-phonon-mode behavior. In In(Ga)-rich GaInNAs alloys the observed splitting of the N_As local mode into a doublet for the N_As-Ga ₁(In₁)In₃(Ga₃) pair-defect of C _3v-symmetry is consistent with our simulated results based on a sophisticated Green's function theory.
