| Outline of Final Research Achievements |
Improvements of both sample quality by using inactive hexagonal boron nitride substrates and device performance of the scanning transmission electron microscope and the angle-resolved photoemission spectroscopy machine have made it possible to perform dramatically advanced research on electronic properties of atomic layers, which include graphene, new 2D materials, and their stacking composites. The followings remarkable results, leading to the development of atomic layer science, have been obtained; discovery of valley Hall effect in bilayer graphene, discovery of 50 K class high temperature superconductivity in FeSe atomic layers, direct observation of electron orbits in high mobility graphene, clarification of electronic structure of 2D semiconductor black phosphorus, elucidation of electronic structure of graphene multilayers, in situ observation of in-plane growth of graphene, and observation of quantum transport phenomena in epitaxial graphene on a tilted SiC substrate.
