Matsunaga Laboratory

Day by day our lives, societies, and the world around us are becoming increasingly more rich, comfortable and convenient. Still, the earth faces many challenging environmental problems and complex issues such as aging societies and we have to tackle these head on to solve them.

In the laboratory, we study the structure of materials and their micro and macroscopic properties from electronic, atomic and molecular aspects, and aim to connect this expertise to development of various innovative materials, and become pioneers in the area of materials science.

Parallel Computer

This is a parallel computer used in our laboratory.

Stereo microscopes

These are used to check the conditions of samples. We have one stereo microscopes.

Imaging Box

This enables us to take nice pictures of small and beautiful objects such as crystals or jewelries.

Water Purification System

This enables purification of water.

Low Speed Precision Cutters

These are used for cutting various types of materials with minimal deformation. We have two cutters.

Precision polishing machines

These are used to polish brittle materials. We have six polishing machines.

Ion Milling Systems

These can produce high-quality TEM specimens with electron transparency.

Magnetron Sputter Coater

This enables nanoscale thin film deposition on the surface of samples.

Precision universal testing machine

This is used to deform materials with measuring displacements and loads.

Semiconductor Parameter Analyzer

This is used for electrical characterization of semiconducting or insulating materials.

Low-Noise Vacuum Prober station

This is used to measure electric properties of materials from low temperature to high temperature.

Spectrophotometer

This enables scientific measurement of reflection and transmission properties of samples as a function of wavelength.

Time-resolved Spectroscopy Equipment

This is used to measure weak phosphorescence spectra and the lifetime.

Xenon Light Sources

This is used to irradiate lights of the specific wavelength domain to materials. We have two xenon light sources.

Draft Chamber

This is a local exhaust ventilation, which is used to treat toxic chemical substances.

Laser microscope

This is used for observing surface morphology in samples.
