Welcome

We are a surface physics research group at the Department of Applied Physics, Osaka University, Japan (group leader; Kazuyuki Sakamoto). Our main interest is to explore exotic low-dimensional physical phenomena of atomic layer crystals formed on solid surfaces by inorganic atoms and/or organic molecules.

Research profile from a booklet of OU.

Lecture to introduce our research (high school level, Japanese only)
