A layered form of graphene shows a rare semimetal state with balanced electrons and holes that becomes a topological ...

ARPES maps the electronic properties, including the band structure and Fermi surface, of the topological insulator bismuth selenide (left). Like graphene, the lower energy valence band of a ...

Scientists have uncovered the detailed structure of the aluminum oxide surface, a challenge that has baffled researchers for decades. Scientists at the TU Wien and the University of Vienna have ...
