Katayama Lab
Machine-translated · View original
A lab that explores materials for next-generation electronic components using thin oxide films.
AboutAbout the lab
Opening up the future of electronics with oxide thin films
The Katayama Lab makes oxide thin films using vacuum deposition techniques and studies how to uncover their functions.
Oxide thin films have properties such as piezoelectricity, sensing functions, and transparent conductivity, and are used in smartphones, in-vehicle devices, medical devices, and more.
Not bound by existing approaches to materials design, the lab creates materials from new perspectives, aiming to contribute to next-generation electronics.
The lab was launched at Tokyo University of Science in April 2026. In addition to synthesizing and evaluating thin films, students also investigate and give presentations on electronic devices.
Key terms
- Oxide thin film
- An oxide made into a film only about a few nanometers thick. The thinner it is, the stronger the electric field applied at the same voltage.
- Electric field
- The voltage divided by the thickness of a material. For the same voltage, it becomes larger the thinner the material is.
- Oxyfluoride
- A substance in which part of an oxide is replaced with fluorine. This lab has developed a technique for synthesizing its thin films at low temperature.
- Dielectric material
- A material that stores electric charge inside when a voltage is applied. It is used in electronic components such as capacitors.

ResearchResearch themes
The Katayama Lab aims to contribute to next-generation electronics by making oxide thin films with vacuum deposition techniques and investigating their functions. The lab brings out the properties of oxides that come into their own when made thin, and searches for functions that have not yet been uncovered.
*Illustrative imageOxide Functions Brought Out by Thinning
Most oxides do not conduct electricity, so an electric field can be applied efficiently by voltage. When they are made as thin as a few nanometers, they show a variety of responses, such as expansion and contraction, charge accumulation, changes in resistance, and memory effects.
*Illustrative imageHigh-Quality Oxide Thin Films Made in a Vacuum
The lab evaporates and deposits materials in a vacuum to make films that contain no impurities and whose structure can be controlled at the atomic level. This vacuum thin-film technology also plays a central role in semiconductor manufacturing.
*Illustrative imageOxyfluorides and Film Lift-Off Technology
The lab also develops its own synthesis methods. These include a technique for synthesizing, at low temperature, oxyfluoride thin films with a wide bandgap by replacing part of an oxide with fluorine, and a technique for peeling off thin films using a water-soluble layer.
*Illustrative imageSearching for Unknown Functions
The lab believes that oxide thin films still hold many functions that have not yet been uncovered, and explores them. It has found oxide thin films that move quickly and greatly in response to light, and new dielectric materials with unprecedented properties.
