Paper Abstract

Another pronounced anomaly of the fundamental properties of photoexcited porous silicon samples is reported -- namely, giant efficiency of sound photogeneration under the irradiation of nanosecond laser pulses. The origin of this anomaly is discussed. The good prospects are demonstrated of techniques based on photoacoustic effect for the studies of fundamental properties of porous Si, in particular, reconstruction of fundamental absorption edge with the option of in-depth profiling, description of the kinetic properties of carriers responsible for the emergence of red-orange emission band, reconstruction of the spectrum of non-radiative transitions.
