Characterization of Heat Propagation along Single Tin Dioxide Nanobelt Using the Thermoreflectance Method
Published online by Cambridge University Press: 01 February 2011
Abstract
In this paper, we studied heat transfer properties of a 230nm wide,450nm thick and 5.4 m long single tin dioxide nanobelt using non-contacted high resolution thermoreflectance imaging technique. Temperature difference across the nanobelt was created by attaching its both ends to a microfabricated thin film heater and sensor pair. High resolution thermal images of the nanobelt and thin film devices were obtained at variant pulsing current amplitudes and frequencies, which allowed us to study the inherent thermal conductance of the nanobelt. Thermal expansion induced thermoreflectance coefficient change is also discussed in this paper.
