Electron density control in tungsten diselenide monolayers via photochlorination
E. Katsipoulaki, G. Vailakis, I. Demeridou +8
Modulation of the Fermi level using an ultraviolet (UV)-assisted photochemical method is demonstrated in tungsten diselenide monolayers. Systematic shifts and relative intensities…
: a defect resilient expanded-lattice high-temperature superconductor
Alexandros Deltsidis, Laura Simonelli, Georgios Vailakis +5
Two-dimensional iron-chalcogenide intercalates display a remarkable correlation of the interlayer spacing with the enhancement of the superconducting critical temperature ().…
Tuning the workfunction of ZnO through surface doping with Mn from first-principles simulations
Andreas Douloumis, Nikolaos R. E. Vrithias, Nikos Katsarakis +2
Surface doping of ZnO allows for tailoring the surface chemistry of the material while preserving the superb electronic structure of the bulk. Apart from obvious changes in adsorpt…
From Order to Disorder of Alkanethiol SAMs on Complex Au (211), (221) and (311) Surfaces: Impact of the Substrate
Dimitrios Stefanakis, Vagelis Harmandaris, Georgios Kopidakis +1
We investigate the impact of the substrate on the structural properties and the morphology of alkanethiol self-assembled monolayers (SAMs) on gold, using first principles calculati…
Stability of metallic edges and Fermi-level pinning in transition-metal dichalcogenide nanoribbons
Daphne Davelou, Georgios Kopidakis, Efthimios Kaxiras +1
Nanoribbons of MoS present a unique electronic structure that consists of a semiconducting bulk bounded by metallic edges; same holds for other Transition-Metal Dichalcogenides…
Transmission thresholds in time-periodically driven nonlinear disordered systems
Magnus Johansson, Georgios Kopidakis, Stefano Lepri +1
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are o…
