I'm looking for accurate data, theoretical and/or experimental, about bandgap alignment in TiO2-Cu2O heterojunctions, for the three TiO2 phases.
I want to grow thin films (e.g. TiO2) on flexible materials. Which substrates could be used? It should support high temperatures. I guess that the adhesion of the sputtered target is an issue, right?
