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) ...
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 ...
Structural, electronic and phononic properties of PtSe2: From monolayer to bulk
(Institute of Physics Publishing, 2018-06)
The layer dependent structural, electronic and vibrational properties of the 1T phase of two dimensional (2D) platinum diselenide are investigated by means of state-of-the-art first-principles calculations. The main findings ...
Theoretical and experimental investigation of conjugation of 1,6-hexanedithiol on MoS2
(Institute of Physics Publishing, 2018-03)
We report an experimental and theoretical investigation of conjugation of 1,6-Hexaneditihiol (HDT) on MoS2 which is prepared by mixing MoS2 structure and HDT molecules in proper solvent. Raman spectra and the calculated ...
Unusual lattice vibration characteristics in whiskers of the pseudo-one-dimensional titanium trisulfide TiS3
(Nature Publishing Group, 2016-09-22)
Transition metal trichalcogenides form a class of layered materials with strong in-plane anisotropy. For example, titanium trisulfide (TiS3) whiskers are made out of weakly interacting TiS3 layers, where each layer is made ...
