Confined Monolayer Ag as a Large Gap 2D Semiconductor
- Ag is a well-known example of metal in its bulkform
- Epitaxially grown monolayer Ag confinedbetween bilayer graphene and SiC is found todevelop a large band gap (> 1eV)
- This finding is a striking example of extremequantum confinement in the monolayer limit
- Development of a time-resolved angle-resolvedphotoemission spectroscopy tool enables us toprobe quantum materials in momentum-,energy-, and time-domains
