Abstract

The paper presents results of photoacoustic studies of thermal and transport properties of silicon samples. It shows for the first time the influence of plasma waves on the Sf/Sr and phase-lag frequency photoacoustic characteristics and describes a procedure leading to the determination of both thermal diffusivity and the life time or the diffusion length of excess carriers from those characteristics.

Keywords:

photoacoustic methods, semiconductors, silicon parameters
