AI Article Synopsis
- Germanene is a two-dimensional honeycomb structure similar to silicene, successfully created on an aluminum substrate (Al(111)).
- The germanene layer exhibits uniform coverage and strong coherence across the Al(111) surface, featuring a (3 × 3) superstructure relative to the substrate's lattice.
- First-principles calculations reveal that germanium atoms organize in a consistent atomic arrangement with a buckled structure.
Article Abstract
Germanene, a 2D honeycomb structure similar to silicene, has been fabricated on Al(111). The 2D germanene layer covers uniformly the substrate with a large coherence over the Al(111) surface atomic plane. It is characterized by a (3 × 3) superstructure with respect to the substrate lattice, shown by low energy electron diffraction and scanning tunnelling microscopy. First-principles calculations indicate that the Ge atoms accommodate in a very regular atomic configuration with a buckled conformation.
