Features of the photoacoustic response formation in nanostructured silicon-based systems with an important specific surface were considered. In particular, influence of the "nanostructured solid / liquid" interface on processes of energy transformation "electromagnetic radiation - sound" was studied. Square-wave modulated laser radiation with a wavelength equal to 532 nm was used for excitation of an informative response. The photoacoustic signal registration in a piezoelectric configuration was performed. The photoacoustic response shapes in the cases of presence and absence of a surface liquid covering layer in contact with the nanostructured surface was experimentally detected. Modification of the response’ shape caused by existence of "nanostructured solid / liquid" interface was analyzed. |
