Microscopy of hydrogen and hydrogen-vacancy defect structures on graphene devices
Dillon Wong, Yang Wang, Wuwei Jin +8
We have used scanning tunneling microscopy (STM) to investigate two types of hydrogen defect structures on monolayer graphene supported by hexagonal boron nitride (h-BN) in a gated…
Optimizing hot electron harvesting at planar metal-semiconductor interfaces with titanium oxynitride thin films
Brock Doiron, Yi Li, Andrei Mihai +8
Understanding metal-semiconductor interfaces is critical to the advancement of photocatalysis and sub-bandgap solar energy harvesting where sub-bandgap photons can be excited and e…
Core electron binding energies of adsorbates on Cu(111) from first-principles calculations
J. Matthias Kahk, Johannes Lischner
Core-level X-ray Photoelectron Spectroscopy (XPS) is often used to study the surfaces of heterogeneous copper-based catalysts, but the interpretation of measured spectra, in partic…
Strong Correlations and d+id Superconductivity in Twisted Bilayer Graphene
Dante M. Kennes, Johannes Lischner, Christoph Karrasch
We compute the phase diagram of twisted bilayer graphene near the magic angle where the occurrence of flat bands enhances the effects of electron-electron interactions and thus unl…
Bound States of Charged Adatoms on MoS2: Screening and Multivalley Effects
Martik Aghajanian, Arash A. Mostofi, Johannes Lischner
Adsorbate engineering is a promising route for controlling the electronic properties of monolayer transition-metal dichalcogenide materials. Here, we study shallow bound states ind…
Material, size and environment dependence of plasmon-induced hot carriers in metallic nanoparticles
Stefano Dal Forno, Luigi Ranno, Johannes Lischner
Harnessing hot electrons and holes resulting from the decay of localized surface plasmons in nanomaterials has recently led to new devices for photovoltaics, photocatalysis and opt…
