Abstract :
The discovery of an unreported phonon in Cd1-xZnx Te is presented. This phonon is only present in thin films, and only when 0<x<1. The phonon is seen at 195 cm-1 and the Raman line is a resonant at an excitation in the vicinity if 600 nm. We believe this phonon is caused by microcrystalline clusters of ZnTe embedded in the Cd1-xZnxTe film, however, this assignation is not final, as further experiments are needed to rule out other possibilities such as a phonon from the ordered phase
