Abstract
The simulation of modulated surface photovoltage (SPV) signals has been demonstrated for nanostructured systems with localized electronic states by using a random walk approach. The proposed algorithm was adapted to a real measurement time regime and allows for the investigation of in-phase and phase-shifted by 90° SPV signals and of frequency, phase angle–amplitude, and temperature dependencies of modulated SPV signals. The simulation of modulated SPV signals can give a strong impact for the interpretation of SPV spectra concerning localized electronic states and related phenomena in nanostructured systems.
