Research Topics

Our main resarch topics are mesoscopic systems,
which consists of superlattice and thin films of
semiconductor, metals and superconductors,
often decorated by microfabrications.
The aim is to seek for quantum mechanical transport phenomena
in low temperature and high magnetic field.
Resarch activities are done in close collaboration with Katsumoto group.

Sorry! Some of the contents below are written in Japanese.
English version will arrive very soon!
