Fig. 5

Surface photovoltage spectra of the typical silicon sample exposed to the acoustic cavitation in cryogenic fluid and annealing in the nitrogen vapor. Dots indicate the experimental data, and solid lines present the result of the fitting procedure. The thin-dash lines show approximation by the Lorentzian model. Inset: the energy band diagram of the Si/SiO2/(CaO-SiO2) structure in dark conditions
