The understanding of phonon-induced charge transport in nanostructured TiO2 is crucial for new generation solar cells, photocatatytic and H2 producing devices. We present results of phonon modes in rutile derived as surface plasmon resonances in the crystalline planes. We find a compound state of two phonon modes centered at 24THz in the bulk, which can exhibit enhanced polaronic state in the nanostructured system. We discuss the possible appearance of high Tc superconductivity

Abstract
The understanding of phonon-induced charge transport in nanostructured TiO2 is crucial for new generation solar cells, photocatatytic and H2 producing devices. We present results of phonon modes in rutile derived as surface plasmon resonances in the crystalline planes. We find a compound state of two phonon modes centered at 24THz in the bulk, which can exhibit enhanced polaronic state in the nanostructured system. We discuss the possible appearance of high Tc superconductivity
