Nanoscale Magnetic Compasses
Hidetsugu Shiozawa, Desai Zhang, Michael Eisterer +4
We have synthesized nanoscale magnetic compasses with high yield. These ferromagnetic iron carbide nano-particles, which are encapsulated in a pair of parallel carbon needles, chan…
Disentangling Vacancy Oxidation on Metallicity-Sorted Carbon Nanotubes
Duncan J. Mowbray, Alejandro Pérez Paz, Georgina Ruiz-Soria +9
Pristine single-walled carbon nanotubes (SWCNTs) are rather inert to O and N, which for low doses chemisorb only on defect sites or vacancies of the SWCNTs at the ppm level…
Polyyne Electronic and Vibrational Properties under Environmental Interactions
M. Wanko, Seymur Cahangirov, Lei Shi +6
Recently, the novel system of linear carbon chains inside of double-walled carbon nanotubes has extended the length of hybridized carbon chains from 44 to thousands of atoms…
Calculation of the graphene C 1 core level binding energy
Toma Susi, Duncan J. Mowbray, Mathias P. Ljungberg +1
X-ray photoelectron spectroscopy (XPS) combined with first principles modeling is a powerful tool for determining the chemical composition and electronic structure of novel materia…
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…
Orbital and spin magnetic moments of transforming 1D iron inside metallic and semiconducting carbon nanotubes
Antonio Briones-Leon, Paola Ayala, Xianjie Liu +6
The orbital and spin magnetic properties of iron inside transforming metallic and semiconducting 1D carbon nanotube hybrids are studied by means of local x-ray magnetic circular di…
