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 ...
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 ...
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 ...
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 ...
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) ...
