Abstract: 
The thermal conductivity kappa of ZnO can be significantly suppressed by alloying with a few percent of S offering the possibility of enhancing the thermoelectric figure of merit ZT. kappa of radio-frequency sputtered wurtzite ZnO1-xSx thin-films was measured in the entire composition range x employing the 3 omega-method. Both, incorporation of low amounts of S in ZnO and of O in ZnS reduce kappa of the ZnO1-xSx-samples compared to the two binary compounds. The origin of the reduction of kappa in the alloys is the formation of localized vibrational modes of S in ZnO and O in ZnS. (C) 2013 AIP Publishing LLC.
