Abstract

The past impossibility to create optical diffraction fringe image out of transparent TiO2(100) substrate was overcome by pumping light pulse of 266-nm wavelength. Thermal diffusivities (D) of TiO2(100) substrate and (Ca1–xSrx)3Co4O9 (0 ≤ x ≤ 0.125) thin films can successfully be determined with a newly proposed transient grating configuration method arising from a generic nanoscale measurement technique. The D values obtained at room temperature were 0.04 cm2/s for the former and 0.07–0.12 cm2/s for the latter, respectively.
