Photovoltaic effect for narrow-gap Mott Insulators - Florida Energy ...

We are focusing our attention to the following class of materialsVO 2LaVO 3 and SrVO 3LaTiO 3 and YTiO 3We would like to study optical properties of these materialsUsing hybrid functionals and many-body perturbation theory.Maitri Warusawithana of NHMFL using MBE is growingepitaxially LaVO 3 films on SrTiO 3We plan to carry out photoconductivity studies of films of such materials.Fast optical pump and probe techniques should probe the decay productsof photo-excited electron/hole pairs.Density functional theory studies of films of the above class of materials.
