| 英文摘要 | Monolayer metal membranes have attracted research attention owing to their fascinating physical properties. Unlike layered materials with weak interlayer van der Waals bonding, metallic monolayer membranes are difficult to exfoliate due to strong metallic bonding between layers. Here, we fabricate free-standing monatomic thick Au membranes and nanoribbons framed in bulk crystals using in situ dealloying inside transmission electron microscope. The Au membranes are robust under high energy electron beam. Monatomic-thick nanoribbons with a minimal width of 0.6 nm are observed. First-principles calculations reveal that zigzag-edged nanoribbons are ferromagnetic with magnetic moments ranging 0.38-0.51 mu B per unit-cell for a width less than 0.9 nm. In addition, a linear relationship between the bond length and the coordination number of atoms is directly investigated using atomic resolution images of monolayer and bilayer Au membranes. This work provides a pathway for direct fabrication of metal membranes and nanoribbons and to achieve novel physical properties. |
