Electron-beam-induced adatom-vacancy-complexes in mono- and bilayer phosphorene
Carsten Speckmann, Andrea Angeletti, Lukáš Kývala +7
Phosphorene, a puckered two-dimensional allotrope of phosphorus, has sparked considerable interest in recent years due to its potential especially for optoelectronic applications w…
Two-dimensional few-atom noble gas clusters in a graphene sandwich
Manuel Längle, Kenichiro Mizohata, Clemens Mangler +4
Van der Waals atomic solids of noble gases on metals at cryogenic temperatures were the first experimental examples of two-dimensional systems. Recently such structures have also b…
Creation of single vacancies in hBN with electron irradiation
Thuy An Bui, Gregor T. Leuthner, Jacob Madsen +6
Understanding electron irradiation effects is vital not only for reliable transmission electron microscopy characterization, but increasingly also for the controlled manipulation o…
Interface effects on titanium growth on graphene
Georg Zagler, Alberto Trentino, Kimmo Mustonen +2
Poor quality interfaces between metal and graphene cause non-linearity and impair the carrier mobility in graphene devices. Here, we use aberration corrected scanning transmission…
Scanning transmission electron microscopy under controlled low-pressure atmospheres
Gregor T. Leuthner, Stefan Hummel, Clemens Mangler +4
Transmission electron microscopy (TEM) is carried out in vacuum to minimize the interaction of the imaging electrons with gas molecules while passing through the microscope column.…
Silicon-carbon bond inversions driven by 60 keV electrons in graphene
Toma Susi, Jani Kotakoski, Demie Kepaptsoglou +8
We demonstrate that 60 keV electron irradiation drives the diffusion of threefold coordinated Si dopants in graphene by one lattice site at a time. First principles simulations rev…
