Abstract
Surface phonons of InP(110) have been studied under high spectral reso lution by Raman scattering. Due to the excellent energy resolution of Raman scattering in this work (maximum 1 cm(-1) = 0.12 meV) it was pos sible to resolve and identify for the first time a surface phonon mode at 350 cm(-1) which appears close in energy to the bulk longitudinal optical phonon at 345 cm(-1). A surface phonon has been predicted theo retically near this frequency and was assigned to a Fuchs-Kliewer phon on; This assignment is, however, not in agreement to our experimental results, which show that this surface phonon is a microscopic surface phonon mode.
