Table 1 Heterotrilayers of X-enes on Gr/SiC.
From: Deposition of topological silicene, germanene and stanene on graphene-covered SiC substrates
X-ene | SiC layer | Gr layer | X-ene layer | \({{\boldsymbol{\varepsilon }}}_{{\bf{G}}{\bf{r}}}\) (%) | εX-ene (%) |
|---|---|---|---|---|---|
Silicene | (\(\sqrt{19}\times \sqrt{19})\) R23.4° | (\(\sqrt{28}\times \sqrt{28})\) R19.1° | (\(\sqrt{12}\times \sqrt{12})\) R30.0° | 3.67 | 1.23 |
Germanene | (\(\sqrt{12}\times \sqrt{12})\) R30.0° | (\(\sqrt{19}\times \sqrt{19})\) R23.4° | (\(\sqrt{7}\times \sqrt{7})\) R19.1° | 0.01 | \(-0.01\) |
Stanene | 4 × 4 | 5 × 5 | (\(\sqrt{7}\times \sqrt{7})\) R19.1° | 0.68 | 0.28 |
