A quantitative study of the photoacoustic (PA) signal dependence on the modulation frequency in semiconductors was performed. The carrier recombination processes were taken into account to calculate the PA signal, considering the thermodiffusion (TD), thermoelastic (TE) and electronic strain (ES) si
