Photopyroelectric Technique in Thermal Diffusivity Determination and Spectroscopic Response of Solid Samples

Conventional photopyroelectric (PPE) measurement of thermal diffusivity of optically opaque sample was done in case of thermally thick sample, but it underwent a great attenuation of signal. In this study, the generalisation of Mandel is and Zver special cases of thermally thin-thick sample has b...
