Reduced Graphene Oxide as a Monolithic Multifunctional Conductive Binder for Activated Carbon Supercapacitors.
Dona TL Galhena, Bernhard C Bayer, Jannik C Meyer, Stephan Hofmann, Gehan AJ Amaratunga
Nov 15, 2018
Using reduced graphene oxide (r-GO) as a multifunctional conductive binder, a simple, cost-effective, and environmentally friendly approach is developed to fabricate activated carbon/reduced graphene oxide (AC/r-GO) composite...
Graphene Liquid Enclosure for Single-Molecule Analysis of Membrane Proteins in Whole Cells Using Electron Microscopy.
Indra N Dahmke, Andreas Verch, Justus Hermannsdörfer, Diana B Peckys, Robert S Weatherup, Stephan Hofmann, Niels de Jonge
May 04, 2018
Membrane proteins govern many important functions in cells via dynamic oligomerization into active complexes. However, analytical methods to study their distribution and functional state in relation to the cellular structure are...

Imaging of Optically Active Defects with Nanometer Resolution.
Jiandong Feng, Hendrik Deschout, Sabina Caneva, Stephan Hofmann, Ivor Lončarić, Predrag Lazić, Aleksandra Radenovic
May 04, 2018
Point defects significantly influence the optical and electrical properties of solid-state materials due to their interactions with charge carriers, which reduce the band-to-band optical transition energy. There has been a...
Empirical Parameter to Compare Molecule-Electrode Interfaces in Large-Area Molecular Junctions.
Marco Carlotti, Saurabh Soni, Andrii Kovalchuk, Sumit Kumar, Stephan Hofmann, Ryan C Chiechi
Jul 01, 2022
This paper describes a simple model for comparing the degree of electronic coupling between molecules and electrodes across different large-area molecular junctions. The resulting coupling parameter can be obtained directly from...
Putting High-Index Cu on the Map for High-Yield, Dry-Transferred CVD Graphene.
Oliver J Burton, Zachary Winter, Kenji Watanabe, Takashi Taniguchi, Bernd Beschoten, Christoph Stampfer, Stephan Hofmann
Jan 25, 2023
Reliable, clean transfer and interfacing of 2D material layers are technologically as important as their growth. Bringing both together remains a challenge due to the vast, interconnected parameter space. We introduce a...
Long-Term Passivation of Strongly Interacting Metals with Single-Layer Graphene.
Robert S Weatherup, Lorenzo D'Arsié, Andrea Cabrero-Vilatela, Sabina Caneva, Raoul Blume, John Robertson, Robert Schloegl, Stephan Hofmann

Growth and Characterisation Studies of Eu<sub>3</sub>O<sub>4</sub> Thin Films Grown on Si/SiO<sub>2</sub> and Graphene.
Razan O M Aboljadayel, Adrian Ionescu, Oliver J Burton, Gleb Cheglakov, Stephan Hofmann, Crispin H W Barnes
Aug 02, 2021
We report the growth, structural and magnetic properties of the less studied Eu-oxide phase, Eu3O4, thin films grown on a Si/SiO2 substrate and Si/SiO2/graphene using molecular beam epitaxy. The X-ray diffraction scans show that...

Introducing Overlapping Grain Boundaries in Chemical Vapor Deposited Hexagonal Boron Nitride Monolayer Films.
Bernhard C Bayer, Sabina Caneva, Timothy J Pennycook, Jani Kotakoski, Clemens Mangler, Stephan Hofmann, Jannik C Meyer
May 04, 2018
We demonstrate the growth of overlapping grain boundaries in continuous, polycrystalline hexagonal boron nitride (h-BN) monolayer films via scalable catalytic chemical vapor deposition. Unlike the commonly reported atomically...
Crystal Orientation Dependent Oxidation Modes at the Buried Graphene-Cu Interface.
Philipp Braeuninger-Weimer, Oliver J Burton, Patrick Zeller, Matteo Amati, Luca Gregoratti, Robert S Weatherup, Stephan Hofmann
Aug 24, 2020
We combine spatially resolved scanning photoelectron spectroscopy with confocal Raman and optical microscopy to reveal how the oxidation of the buried graphene-Cu interface relates to the Cu crystallographic orientation. We...
Giant photoluminescence enhancement in MoSe2 monolayers treated with oleic acid ligands.
Arelo OA Tanoh, Jack Alexander-Webber, Ye Fan, Nicholas Gauriot, James Xiao, Raj Pandya, Zhaojun Li, Stephan Hofmann, Akshay Rao
Aug 19, 2021
The inherently low photoluminescence (PL) yields in the as prepared transition metal dichalcogenide (TMD) monolayers are broadly accepted to be the result of atomic vacancies (i.e., defects) and uncontrolled doping, which give...
