Paper Abstract

The amplitude and phase reflection spectra of InAs have been determined in the far infrared at room temperature by dispersive Fourier transform spectrometry and used to calculate the optical constants, dielectric response functions, and the anharmonic damping function of the q = 0 transverse optic mode. The overall features of the optical and dielectric functions are in good agreement with published work, but a number of new features associated with phonon combination bands are revealed for the first time, particularly in the damping function. The application of such measurements to the determination of improved values of critical point phonon frequencies in InAs and other zincblende structure crystals is discussed.
