Two-dimensional transition metal dichalcogenides under electron irradiation: defect production and doping
Hannu-Pekka Komsa, Jani Kotakoski, Simon Kurasch +3
Using first-principles atomistic simulations, we study the response of atomically-thin layers of transition metal dichalcogenides (TMDs) - a new class of two-dimensional inorganic…
Are we van der Waals ready?
T. Björkman, A. Gulans, A. V. Krasheninnikov +1
We apply a range of density-functional-theory-based methods capable of describing van der Waals interactions to weakly bonded layered solids in order to investigate their accuracy…
Ion irradiation tolerance of graphene as studied by atomistic simulations
E. H. Åhlgren, J. Kotakoski, O. Lehtinen +1
As impermeable to gas molecules and at the same time transparent to high-energy ions, graphene has been suggested as a window material for separating a high-vacuum ion beam system…
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…
