Researchers have discovered the superconductivity of Ti4O7 and γ-phase titanium pentoxide (γ-Ti3O5) films. This achievement has promoted the development of the theoretical basis of nanomaterials, which may be used in the development of ultra-fast computers.

    Many people are still familiar with titanium dioxide (TiO2), a chemical commonly used in sunscreen and paint whitening agents. What is not usually known is that titanium oxides with high atomic numbers and titanium oxides with higher oxygen atoms than TiO have great potential for applications in the next generation of electronic devices. So at present, this kind of material has been strengthened for related research.

    Researchers at Tokyo University of Technology have discovered superconductivity in two ultra-thin film forms, titanium oxides with high atomic numbers. When the thickness of the material is about 120 nm, it begins to show the superconducting properties that have just been explored.

Previously, the two materials existed only in granular form, and related studies were carried out. In this form, they exhibit the opposite properties of the insulator and the conductor. Therefore, the use of this material to form conductive thin films is considered to be a great advance in basic physics.

    So far,however， no one has been able to pinpoint exactly how these titanium oxides produce superconductivity.
