Anomalous Raman Spectra and Thickness Dependent Electronic properties of WSe2
H. Sahin, S. Tongay, S. Horzum +5
Typical Raman spectra of transition metal dichalcogenides (TMDs) display two prominent peaks, E2g and A1g, that are well separated from each other. We find that these modes are deg…
Adsorption of Alkali, Alkaline Earth and Transition Metal Atoms on Silicene
Hasan Sahin, Francois M. Peeters
The adsorption characteristics of alkali, alkaline earth and transition metal adatoms on silicene, a graphene-like monolayer structure of silicon, are analyzed by means of first-pr…
Vibrational properties of nanographene
Sandeep Kumar Singh, F. M. Peeters
The eigenmodes and the vibrational density of states of the ground state configuration of graphene clusters are calculated using atomistic simulations. The modified Brenner potenti…
Adsorption of titanium and titanium dioxide on graphene: n and p-type doping
Jozef Sivek, Ortwin Leenaerts, Bart Partoens +1
Ab initio calculations within the density-functional theory formalism are performed to investigate the ground state, electric charge doping, and electronic properties of titanium a…
