Raman studies of cubic BC₂N, a new superhard phase

Abstract

Abstract UV and visible Raman scattering spectra of a new superhard phase, cubic BC 2 N, were measured for the first time. The Raman band at 1326 cm −1 was attributed to the longitudinal optical (LO) mode of cubic BC 2 N, whereas the transverse optic (TO) mode is missing in the spectra. Raman scattering was found to be a sensitive method for detecting new diamond‐like BCN phases. Copyright © 2004 John Wiley & Sons, Ltd.
