Two-layer model for photopyroelectric spectroscopy
Journal de Physique IV : Proceedings
This paper presents a one-dimensional theory which describes the dependence of the photopyroelectric induced signal on the optical and thermal properties of a two-layer sample, for example a thin film deposited on a substrate. Several computer simulations were performed in order to determine the validity of this model for a wide range of wavelengths and modulation frequencies.doi:10.1051/jp4:1994790 fatcat:2krrcoaqizenxhmjoss3qrjtue
