Outline Activities
We research on topics of eco-materials and eco–devices.

1. Ultrasonic gas sensors
For a hydrogen energy society such as using fuel cells, it is necessary to use a small and low cost hydrogen sensor. We study a hydrogen sensor using ultrasonics for practical use. We are also challenging in a new method of measuments as an application of the ultrasonic.

2. Semiconductor physics and devices
(1) A new solar cell process and materials
(2) Si/3C-SiC/Nano-crystal diamond film growth and new generation power devices

3. Hydrogen generating, adsorboing or absorbing materials and its application
We study on a new application and method to generate, adsorb or absorb hydrogen using natural materials around you.
