Title: Oxygen vibrational modes in ZnS 1–xO x alloys

Abstract

ZnS 1-xO x alloy films were studied via resonant Raman spectroscopy. Films with low oxygen content exhibit ZnS longitudinal optical modes and additional modes attributed to O local vibrational modes (LVMs). The frequencies of these modes are explained by a simple mass-defect model. As the O content increases, pairs and larger clusters form, causing the O mode to transition from an LVM to a delocalized phonon. The composition dependence of the modes shows agreement with the modified random element isodisplacement model. In conclusion, low-temperature measurements show the O-related mode is composed of multiple features, attributed to zincblende and wurtzite structural regions.
