Notes:
In this paper we combine the use of photo-thermal techniques, Thermal lens (TL)spectrometry, Photoacoustic and heat capacity measurements to determine the optical pathdependence with temperature (ds/dT) of a polycrystalline 3C-SiC sample. Results obtained for thepolycrystalline sample with the TL technique show that ds/dT is negative at room temperature. Thismeans that the thermal lens formed in 3C-SiC acts as a divergent lens when light impinges thesample. Our measurements, demonstrate that photo-thermal techniques can be used to obtainthermal parameters in circumstances where other techniques cannot be used, for example, in harshenvironments
