description: Photo-induced current through nanocomposite heterojunction structures consisting of a TiO2 coating activated with embedded gold nanoparticles on top of Si, SiO2, and columnar structured SiO2 is studied. The highest photo-activity in the visible part of the spectrum is found in the composite containing pillar-like silicon dioxide nanostructures. Experimental results were qualitatively explained on the basis of Franz-Keldysh effect taking into account the influence of electrical inhomogeneities appearing at charged nanoparticles. The features of the effect of gold nanoparticles on the energy and optical properties of the obtained nanocomposites are studied. High photoactivity of nanocomposite in the visible part of the spectrum containing columnar nanostructures of silicon dioxide was found. It is established that processes at the interface play an important role in charge carrier photo-generation which opens a new opportunity to tune the photo-response of a nanocomposite via changing heterostructure topology.
