Graphene-Confined Growth of Few-Layer PtSe2 via One-Step Selenization
Timea Ema Krajčovičová, Peter Kotrusz, Viera Skákalová +5
Platinum diselenide (PtSe), a member of the transition metal dichalcogenide (TMD) family, is a promising material for next-generation electronic and optoelectronic applications…
Hexatic Phase in Covalent Two-Dimensional Silver Iodide
Thuy An Bui, David Lamprecht, Jacob Madsen +10
According to the Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory, the transition from a solid to liquid in two dimensions proceeds through an orientationally ordered liqui…
Towards Exotic Layered Materials: 2D Cuprous Iodide
Kimmo Mustonen, Christoph Hofer, Peter Kotrusz +10
Heterostructures composed of two-dimensional (2D) materials are already opening many new possibilities in such fields of technology as electronics and magnonics, but far more could…
Picometer-precision few-tilt ptychotomography of 2D materials
Christoph Hofer, Kimmo Mustonen, Viera Skakalova +1
From ripples to defects, edges and grain boundaries, the 3D atomic structure of 2D materials is critical to their properties. However the damage inflicted by conventional 3D analys…
Enhanced Tunnelling in a Hybrid of Single-Walled Carbon Nanotubes and Graphene
Yongping Liao, Kimmo Mustonen, Semir Tulic +9
Transparent and conductive films (TCFs) are of great technological importance. The high transmittance, electrical conductivity and mechanical strength make single-walled carbon nan…
Direct visualization of the 3D structure of silicon impurities in graphene
Christoph Hofer, Viera Skakalova, Mohammad Reza Ahmadpour Monazam +4
We directly visualize the three-dimensional (3D) geometry and dynamics of silicon impurities in graphene as well as their dynamics by aberration-corrected scanning transmission ele…
Computational insights and the observation of SiC nanograin assembly: towards 2D silicon carbide
Toma Susi, Viera Skakalova, Andreas Mittelberger +6
While an increasing number of two-dimensional (2D) materials, including graphene and silicene, have already been realized, others have only been predicted. An interesting example i…
Electronic Transport in Composites of Graphite Oxide with Carbon Nanotubes
Viera Skakalova, Viliam Vretenar, Lubomir Kopera +5
We show that the presence of electrically insulating graphite oxide (GO) within a single wall carbon nanotube network strongly enhances electrical conductivity, whereas reduced gra…
Transconductance fluctuations as a probe for interaction induced quantum Hall states in graphene
Dong Su Lee, Viera Skakalova, R. Thomas Weitz +2
Transport measurements normally provide a macroscopic, averaged view of the sample, so that disorder prevents the observation of fragile interaction induced states. Here, we demons…
An accurate measurement of electron beam induced displacement cross sections for single-layer graphene
J. C. Meyer, F. Eder, S. Kurasch +9
We present an accurate measurement and a quantitative analysis of electron-beam induced displacements of carbon atoms in single-layer graphene. We directly measure the atomic displ…
Raman Scattering at Pure Graphene Zigzag Edges
Benjamin Krauss, Péter Nemes-Incze, Viera Skakalova +3
Theory has predicted rich and very distinct physics for graphene devices with boundaries that follow either the armchair or zigzag crystallographic directions. A prerequisite to di…
Charged defects in graphene and the ionicity of hexagonal boron nitride in direct images
Jannik C. Meyer, Simon Kurasch, Hye Jin Park +10
We report on the detection and charge distribution analysis for nitrogen substitutional dopants in single layer graphene membranes by aberration-corrected high-resolution transmiss…
Growth and properties of few-layer graphene prepared by chemical vapor deposition
Hye Jin Park, Jannik Meyer, Siegmar Roth +1
The structure, and electrical, mechanical and optical properties of few-layer graphene (FLG) synthesized by chemical vapor deposition (CVD) on a Ni coated substrate were studied. A…
Correlation between resistance fluctuations and temperature dependence of conductivity in graphene
Viera Skakalova, Alan B. Kaiser, Jai Seung Yoo +2
The weak temperature dependence of the resistance R(T) of monolayer graphene1-3 indicates an extraordinarily high intrinsic mobility of the charge carriers. Important complications…
