Ultra-clean isotope engineered double-walled carbon nanotubes as tailored hosts to trace the growth of carbyne
Weili Cui, Ferenc Simon, Yifan Zhang +3
Increasing attention is currently given to carbyne, the sp1 hybridized one-dimensional carbon allotrope, because of its predicted outstanding mechanical, optical, and electrical pr…
Synthesis of nitrogen doped single wall carbon nanotubes with caffeine
Filippo Fedi, Oleg Domanov, Paola Ayala +1
Nitrogen doped single wall carbon nanotubes have many functional benefits. Doping opens the possibility to control the electronic energy levels, surface energy, surface reactivity…
Oxidation stability of confined linear carbon chains, carbon nanotubes, and graphene nanoribbons as 1D nanocarbons
Weili Cui, Takeshi Saito, Paola Ayala +2
Three typical one-dimensional (1D)/quasi-1D nanocarbons, linear carbon chains, carbon nanotubes, and graphene nanoribbons have been proven to grow inside single-wall carbon nanotub…
Templated direct growth of ultra-thin double-walled carbon nanotubes
Lei Shi, Jinquan Wei, Kazuhiro Yanagi +5
Double-walled carbon nanotubes (DWCNTs) combined the advantages of multi-walled (MW-) and single-walled (SW-) CNTs can be obtained by transforming the precursors (e.g. fullerene, f…
Extraction of Linear Carbon Chains Unravels the Role of the Carbon Nanotube Host
Lei Shi, Kazuhiro Yanagi, Kecheng Cao +3
Linear carbon chains (LCCs) have been shown to grow inside double-walled carbon nanotubes (DWCNTs) but isolating them from this hosting material represents one of the most challeng…
Electronic band gaps of confined linear carbon chains ranging from polyyne to carbyne
Lei Shi, Philip Rohringer, Marius Wanko +7
Ultra long linear carbon chains of more than 6000 carbon atoms have recently been synthesized within double-walled carbon nanotubes, and they show a promising new route to one--ato…
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…
On the bonding environment of phosphorus in purified doped single-walled carbon nanotubes
Georgina Ruiz-Soria, Toma Susi, Markus Sauer +3
In this work, phosphorous-doped single-walled carbon nanotubes have been synthesized by the thermal decomposition of trimethylphosphine using a high-vacuum chemical vapor depositio…
Raman and XPS analyses of pristine and annealed N-doped double-walled carbon nanotubes
Lei Shi, Markus Sauer, Oleg Domanov +3
N-doped single/multi-walled carbon nanotubes (CNTs) were studied for long time from synthesis to properties. However, the stability of N in the CNT lattice still needs further deve…
Confined linear carbon chains: A route to bulk carbyne
Lei Shi, Philip Rohringer, Kazu Suenaga +6
The extreme instability and strong chemical activity of carbyne, the infinite sp1 hybridized carbon chain, are responsible for its low possibility to survive in ambient conditions.…
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…
