Square ice in graphene nanocapillaries
G. Algara-Siller, O. Lehtinen, F. C. Wang +5
Adsorbed layers of water are ubiquitously present at surfaces and fill in microscopic pores, playing a central role in many phenomena in such diverse fields as materials science, g…
Implantation and atomic scale investigation of self-interstitials in graphene
Ossi Lehtinen, Nilesh Vats, Gerardo Algara-Siller +2
Crystallographic defects play a key role in determining the properties of crystalline materials. The new class of two-dimensional materials, foremost graphene, have enabled atomica…
The pristine atomic structure of MoS2 monolayer protected from electron radiation damage by graphene
Gerardo Algara-Siller, Simon Kurasch, Mona Sedighi +2
Materials can, in principle, be imaged at the level of individual atoms with aberration corrected transmission electron microscopy. However, such resolution can be attained only wi…
Twisted bi-layer graphene: microscopic rainbows
J. Campos-Delgado, G. Algara-Siller, C. N. Santos +2
Twisted bi-layer graphene (tBLG) has recently attracted interest due to the peculiar electrical properties that arise from its random rotational configurations. Our experiments on…
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…
From Graphene constrictions to single carbon chains
A. Chuvilin, J. C. Meyer, G. Algara-Siller +1
We present an atomic-resolution observation and analysis of graphene constrictions and ribbons with sub-nanometer width. Graphene membranes are studied by imaging side spherical ab…
