Title: Plasmon mediated cathodic photocurrent generation in sol-gel synthesized doped SrTiO{sub 3} nanofilms

Thin films of SrTiO{sub 3} (STO) and Rh-doped SrTiO{sub 3} (Rh-STO) were synthesized by sol-gel method and loaded with Ag nanoparticles. Pristine STO films exhibited anodic photocurrent while Rh-STO exhibited cathodic photocurrent. An enhancement in the overall cathodic photocurrent is observed with Ag nanoparticle loading and an additional enhancement in the visible light range is seen from the incident photon-to-current efficiency spectrum due to synergetic effect of Rh doping and Ag loading in STO.
