Abstract
A calculation is presented on the evolution of longitudinal and transv erse optical phonons as a function of the concentration parameter x in the system Zn, Cd1-xSe. The calculation is based in an isodisplacemen t model of the atoms which include interactions to first and second ne ighbors. The model is fitted to Raman measurements carried out on thin -film samples grown by Close Spaced Vapor Transport (CSVT). Comparison to the experimental data allows to conclude that the x-dependence of these optical modes corresponds to an intermediate-mode behavior. Copy right (C) 1996 Elsevier Science Ltd
