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…
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…
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…
Dual origin of defect magnetism in graphene and its reversible switching by molecular doping
R. R. Nair, I-Ling Tsai, M. Sepioni +7
A possibility to control magnetic properties by using electric fields is one of the most desirable characteristics for spintronics applications. Finding a suitable material remains…
