摘要:
The electronic structure of the (3x3)-ordered phase of a silicon (Si) layer on Al(111) has been studied by angle-resolved photoemission spectroscopy using synchrotron radiation and modeled by a trial atomic model. A closed Fermi surface originating from a linearly dispersing band is identified. A band structure calculation of a trial atomic model of the honeycomb silicene on Al(111) implies that the metallic band originates from the Al-Si hybrid state that has the Dirac-cone-like dispersion curve. The Si layer on Al(111) can be a model system of Xenes to realize the massless electronic system through the overlayer-substrate interaction.
