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…
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…
Spin-half paramagnetism in graphene induced by point defects
R. R. Nair, M. Sepioni, I-Ling Tsai +6
Using magnetization measurements, we show that point defects in graphene - fluorine adatoms and irradiation defects (vacancies) - carry magnetic moments with spin 1/2. Both types o…
Cutting and controlled modification of graphene with ion beams
O. Lehtinen, J. Kotakoski, A. V. Krasheninnikov +1
Using atomistic computer simulations, we study how ion irradiation can be used to alter the morphology of a graphene monolayer by introducing defects of specific type, and to cut g…
Crater formation: can macroscopic scaling laws be used in microscopic cratering?
E. M. Bringa, K. Nordlund, J. Keinonen
Using classical molecular dynamics simulations we examine the formation of craters during 0.4 - 100 keV Xe bombardment of Au. Our simulation results, and comparison with experiment…
