Platform and Framework for Time-Resolved Nanoscale Thermal Transport Measurements in STEM
Mairi McCauley, Joel Martis, Ondrej L. Krivanek +12
Understanding heat transport at the nanometer scale is critical for semiconductor devices, quantum materials, and thermal management of nanostructures, yet direct local measurement…
Intrinsic core level photoemission of suspended graphene
Toma Susi, Mattia Scardamaglia, Kimmo Mustonen +11
X-ray photoelectron spectroscopy of graphene is important both for its characterization and as a model for other carbon materials. Despite great recent interest, the intrinsic phot…
Revealing the 3D Structure of Graphene Defects
Christoph Hofer, Christian Kramberger, Mohammad Reza Ahmadpour Monazam +5
We demonstrate insights into the three-dimensional structure of defects in graphene, in particular grain boundaries, obtained via a new approach from two transmission electron micr…
Analysis of point defects in graphene using low dose scanning transmission electron microscopy imaging and maximum likelihood reconstruction
Christian Kramberger, Andreas Mittelberger, Christoph Hofer +1
Freestanding graphene displays an outstanding resilience to electron irradiation at low electron energies. Point defects in graphene are, however, subject to beam driven dynamics.…
Automated image acquisition for low-dose STEM at atomic resolution
Andreas Mittelberger, Christian Kramberger, Christoph Hofer +2
Beam damage is a major limitation in electron microscopy that becomes increasingly severe at higher resolution. One possible route to circumvent radiation damage, which forms the b…
Insights into radiation damage from atomic resolution scanning transmission electron microscopy imaging of mono-layer CuPcCl films on graphene
Andreas Mittelberger, Christian Kramberger, Jannik C. Meyer
Atomically resolved images of monolayer organic crystals have only been obtained with scanning probe methods so far. On the one hand, they are usually prepared on surfaces of bulk…
Electron-Beam Manipulation of Silicon Dopants in Graphene
Mukesh Tripathi, Andreas Mittelberger, Nicholas A. Pike +5
The direct manipulation of individual atoms in materials using scanning probe microscopy has been a seminal achievement of nanotechnology. Recent advances in imaging resolution and…
Buckyball sandwiches
Rasim Mirzayev, Kimmo Mustonen, Mohammad R. A. Monazam +6
Two-dimensional (2D) materials have considerably expanded the field of materials science in the last decade. Even more recently, various 2D materials have been assembled into verti…
Cleaning graphene: comparing heat treatments in air and in vacuum
Mukesh Tripathi, Andreas Mittelberger, Kimmo Mustonen +4
Surface impurities and contamination often seriously degrade the properties of two-dimensional materials such as graphene. To remove contamination, thermal annealing is commonly us…
Unraveling the 3D atomic structure of a suspended graphene/hBN van der Waals heterostructure
G. Argentero, A. Mittelberger, M. R. A. Monazam +7
In this work we demonstrate that a free-standing van der Waals heterostructure, usually regarded as a flat object, can exhibit an intrinsic buckled atomic structure resulting from…
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…
Single-atom spectroscopy of phosphorus dopants implanted into graphene
Toma Susi, Trevor P. Hardcastle, Hans Hofsäss +7
One of the keys behind the success of the modern semiconductor technology has been the ion implantation of silicon, which allows its electronic properties to be tailored. For simil…
