2D vibrational properties of epitaxial silicene on Ag(111)

Solonenko, Dmytro; Gordan, Ovidiu D.; Le Lay, Guy; Şahin, Hasan; Cahangirov, Seymur; Zahn, Dietrich R. T.; Vogt, Patrick (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

Solonenko, Dmytro; Dzhagan, Volodymyr; Cahangirov, Seymur; Bacaksız, Cihan; Şahin, Hasan; Zahn, Dietrich R. T.; Vogt, Patrick (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) ...
