Twofold SRO films: Investigation of the photoelectric properties of MOS-like structures

► Twofold SRO films interesting optical and electrical properties as: strong photoluminescence (red to near infrared), photocurrent and photoconduction were observed and analyzed. ► MOS-like structures with twofold SRO film as the active layer have shown an enhanced in the conductivity under illumination different conditions. ► Twofold SRO layer were fabricated in order to have a barrier to isolate the silicon substrate from the active SRO layer and to observe the photoelectric effects of the first SRO layer. ► A possible application of this photo-effect can be used to increase the response of photodetectors and silicon solar cells.
