2D vibrational properties of epitaxial silicene on Ag(111)
(IOP Publishing, 2017-03)
The two-dimensional silicon allotrope, silicene, could spur the development of new and original concepts in Si-based nanotechnology. Up to now silicene can only be epitaxially synthesized on a supporting substrate such as ...
Hydrogen-induced sp2-sp3 rehybridization in epitaxial silicene
(American Physical Society, 2017-12)
We report on the hydrogenation of (3×3)/(4×4) silicene epitaxially grown on Ag(111) studied by in situ Raman spectroscopy and state-of-the-art ab initio calculations. Our results demonstrate that hydrogenation of (3×3)/(4×4) ...
