Abstract
We report on the Raman spectra of Ti 3SiC 2 (312), M 2AlC (211) (M=Ti, V, Cr, and Nb) and Ti 4AlN 3 (413), as representative compounds from the family of M n+1AX n phases. Intense and narrow first-order Raman peaks are observed, and we present an analysis of the spectra based on symmetry considerations and from results of first-principles calculations of phonon frequencies. The agreement between experimental and calculated mode energies is excellent. The identification of the modes enables application of Raman scattering as a diagnostic tool for the detailed study of the structural and physical properties of this family of compounds and their engineered solid solutions.
