About us

Welcome to the homepage of Research Laboratory of Surface Science (Yokoya/Muraoka Group) at Okayama University.
Our interests are to synthesize new functional materials and to reveal the origin of their functionalities from the viewpoint of electronic structures. We utilize various techniques in solid state chemistry and high-resolution photoemission spectroscopy to approach our goals.
We are currently recruiting graduate students (master and Ph.D cource students) to our laboratory.
