Effect of phonon anharmonicity on thermal conductivity of ZnTe Thin films

The ZnTe thin film is a potential material for optoelectronic devices in extreme temperature and radiation environments. In this report, the thermal conductivity of ZnTe films is measured non-invasively using the micro-Raman method and correlated with the phonon anharmonic effect.
