Description

Technical field [0001] The invention belongs to the technical field of thin film materials, and specifically relates to an organic superlattice titanated 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 can prepare superlattices with better performance. The difference in the energy band structure of adjacent substances in the superlattice can increase the effective absorption of light in different wavelength ranges by the film. The surface effect and tunneling effect of the superlattice also have an impact on the transmission of electrons. The materials with this structure have greatly attracted solar cell researchers. Summary of the invention [0003] The purpose of the present invention is to provide an organi...
