Paper Abstract

Recently, porous silicon has been extensively studied due to its luminescence properties and some interesting features for micromechanical technology, characteristics that have led to a wide range of applications, from electro-optical devices to IR radiation detectors and gas sensors. It is therefore very important to obtain a complete description of this material, measuring its optical, electronic, and thermal properties. Following an introduction of the production process of porous silicon and its main physical and morphological characteristics, a review is presented of the possible applications of photothermal and photoacoustic techniques for the measurement of optical absorption and electronic and thermal transport properties.
