In this paper we combine the use of photo-thermal techniques, Thermal lens (TL)
spectrometry, Photoacoustic and heat capacity measurements to determine the optical path
dependence with temperature (ds/dT) of a polycrystalline 3C-SiC sample. Results obtained for the
polycrystalline sample with the TL technique show that ds/dT is negative at room temperature. This
means that the thermal lens formed in 3C-SiC acts as a divergent lens when light impinges the
sample. Our measurements, demonstrate that photo-thermal techniques can be used to obtain
thermal parameters in circumstances where other techniques cannot be used, for example, in harsh
environments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
