Abstract

The fabrication of heterojunction by growing a La_0.29Pr _0.38Ca_0.33MnO₃ (LPCM) film on the 0.5 wt% Nb-doped SrTiO₃ (STON) substrate was discussed. It was shown that the heterojunction exhibits a significant photovoltaic effect. It was observed that the photovoltage on the two electrodes LPCM and STON increases almost linealy with the power of the laser beam at a rate of ∼0.19 V/W and no tendency to saturation was observed up to the light power of 100 mW. It was shown that the lifetime of the extra carriers was between 7 and 9 ms, obtained from the decay of photovoltage after shutting down light illumination.
