Masumoto Lab
Machine-translated · View original
A thin-film lab that gives a single material two or more functions.

AboutAbout the lab
Two or more functions in a single material.
The Masumoto Lab researches the development of new intelligent materials that combine multiple material functions.
It works with magnetic-dielectric materials that have a multilayer structure of metal and ceramics, and with osteoconductive implant materials made by modifying the surface of titanium.
Its most important theme is 'integrated functional materials,' which give a single material two or more functions.
To make materials, the lab uses vapor-phase methods such as plasma, sputtering, and chemical vapor deposition (CVD), as well as pressure sintering.
Key terms
- Integrated functional materials
- Materials that give a single material two or more functions, combining separate properties such as magnetic and dielectric properties
- Sputtering
- A method in which ions strike a material in a vacuum to knock atoms loose, which then settle as a thin film on another substrate
- Osteoconductivity
- The property by which bone grows into the surface of a material and bonds firmly with it

ResearchResearch themes
By designing materials, properties, and processes together, the lab aims to create new functions and improve material performance. To advance development efficiently, it values joint research with different fields inside and outside the university.
*Illustrative imageMetal–ceramic nanocomposite thin films
The lab develops thin-film materials that show the 'tunnel magneto-dielectric effect' and the 'tunnel magneto-optical effect,' both discovered in the lab. It is also searching for new materials with two or more functions.
*Illustrative imageNext-generation optical filter thin films
Using sputtering, the lab makes multilayer dielectric thin films whose refractive index is varied gradually. It evaluates the films' structure, microstructure, composition, and optical properties to develop high-performance optical filters.
*Illustrative imageBiocompatible thin-film materials
The lab works on developing implant materials with improved biocompatibility through surface treatment using electron cyclotron resonance plasma.
