Abstract
A new photothermal technique is proposed. It is based on the temperatu re characteristic of the dielectric constant of light-irradiated mater ial. A quantitative derivation is presented for the alternating capaci tance variation in terms of the optical, thermal, dielectric and geome tric parameters of the system. The experimental results for TiO2-Bi2Ti O4O11 ceramics, lead zirconate titanate ceramics and ZnSe semiconducto r are shown, where the observed signals agree with theoretical ones ve ry well.
