Abstract

Analysis of SnO₂ nanobelt thermal conductivity data is performed by two methods: the adjustable cutoff Callaway method, and the real dispersion method. Analyses suggest a possible enhancement of the Umklapp scattering rate of 3 to 6 times that in the bulk material, although hotspots or other contact effects are not ruled out as alternative effects affecting the curves. The thermal conductivity of a 37 nm thick SnO₂ nanobelt was measured. In this paper we show two different, preliminary analyses of the data. An appendix briefly explains the approaches used in the analyses.
