WebNov 28, 2016 · For the lattice-distorted TiO 2 film, a gradient of the lattice parameter was formed, leading to the forming of potential slopes of the valence band maximum and conduction band minimum as confirmed by DFT calculations. The potential slopes promote effective separation of the electron-hole to improve the photocatalytic performance.

Here are a few examples of both theoretical and experimental research efforts to illustrate the broad range of topics: • Theory has shown that polymer chains that have been looped and formed into rings undergo a Peierls transition. These rings demonstrate a persistent current, and the Peierls distortion can be modified by modulating the magnetic flux through the loop.
