Photopyroelectric (PPE) calorimetry of composite materials

On the optimization of experimental parameters in photopyroelectric investigation of thermal diffusivity of solids

“…Different solutions have been proposed in order to obtain correct values of thermal diffusivity. Some are based on non-contact techniques as photothermal radiometry (PTR) [17][18][19], others try to modify the experimental set-up of the PPE technique itself. Salazar et al [5][6][7], for instance, used transparent electrodes (ITO) deposited on the sensor (LiTaO 3 ) surface, and introduced a self-normalization procedure [6,7].…”
