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…
Numerical correction of anti-symmetric aberrations in single HRTEM images of weakly scattering 2D-objects
Ossi Lehtinen, Dorin Geiger, Zhongbo Lee +4
Here, we present a numerical post-processing method for removing the effect of anti-symmetric residual aberrations in high-resolution transmission electron microscopy (HRTEM) image…
Non-invasive transmission electron microscopy of vacancy defects in graphene produced by ion irradiation
Ossi Lehtinen, I-Ling Tsai, Rashid Jalil +4
Irradiation with high-energy ions has been widely suggested as a tool to engineer properties of graphene. Experiments show that it indeed has a strong effect on its transport, magn…
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…
