Most of these anomalous Raman modes have been attributed to local vibrational modes of impurities or defects. However, we will show that most of the observed modes correspond to wurtzite-ZnO silent modes allowed by the breakdown of the translational crystal symmetry induced by defects and impurities. eng info:eu-repo/semantics/openAccess Silent Raman modes in zinc oxide and related nitrides info:eu-repo/semantics/article
