Outline of Final Research Achievements

Topological insulators are materials which exhibit a fundamentally new physical phenomena that were first predicted by theorists. Recently, SmO is predicted to have a topological nontrivial ground state at ambient pressure.
In this study, we succeeded to fabricate SmO thin films by molecular beam epitaxy method controlled precisely adjusting the substrate temperature and oxygen partial pressure.
