Description

technical field [0001] The invention belongs to the technical field of thin film materials, and in particular relates to an organic superlattice titanite transition metal oxide mixed thin film infrared photosensitive material. Background technique [0002] In the past 10 years, with the development of science and technology, using the small size effect, surface effect and quantum tunneling effect of materials, combining nanotechnology with traditional surface technology, superlattices with more excellent performance can be prepared. The different energy band structures of the adjacent materials of the superlattice can increase the effective absorption of light in different wavelength ranges by the thin film. The surface effect and tunnel effect of the superlattice also have an impact on the transport of electrons. Materials that enable this structure are of great interest to solar cell researchers.
