Journal ArticleDOI
Scaling of the Surface Plasmon Resonance in Gold and Silver Dimers Probed by EELS
Shima Kadkhodazadeh,Jakob Rosenkrantz de Lasson,Marco Beleggia,Harald Kneipp,Jakob Birkedal Wagner,Katrin Kneipp +5 more
TL;DR: In this article, the relationship between the surface plasmon resonance (SPR) wavelength and interparticle distance was investigated in the range 0.1R < d < R. The authors showed that the decaying exponential description of the fractional SPR wavelength with d/2R holds valid only over a limited range of d.
Journal ArticleDOI
Growth Mechanism of Single-Walled Carbon Nanotubes on Iron− Copper Catalyst and Chirality Studies by Electron Diffraction
Maoshuai He,Bilu Liu,Bilu Liu,Alexander I. Chernov,Elena D. Obraztsova,Inkeri Kauppi,Hua Jiang,Ilya V. Anoshkin,Filippo Cavalca,Thomas Willum Hansen,Jakob Birkedal Wagner,Albert G. Nasibulin,Esko I. Kauppinen,Juha Linnekoski,Marita Niemelä,Juha Lehtonen +15 more
TL;DR: In this article, single-walled carbon nanotubes grown on an atomic layer deposition prepared bimetallic FeCu/MgO catalyst were evaluated quantitatively using nanobeam electron diffraction.
Journal ArticleDOI
Discrete Dynamics of Nanoparticle Channelling in Suspended Graphene
Timothy J. Booth,Filippo Pizzocchero,Henrik Andersen,Thomas Willum Hansen,Jakob Birkedal Wagner,Joerg R. Jinschek,Rafal E. Dunin-Borkowski,Ole Hansen,Peter Bøggild +8 more
TL;DR: A previously undescribed stepwise oxidation of mono- and few layer suspended graphene by silver nanoparticles in situ at subnanometer scale in an environmental transmission electron microscope is observed and the implications for accurate nanoscales patterning of nanoscale systems are discussed.
Journal ArticleDOI
Catalysts under Controlled Atmospheres in the Transmission Electron Microscope
TL;DR: In this paper, the authors provide an account of best practice using environmental transmission electron microscopy on catalytic systems illustrated using select examples from the literature showing how in situ microscopy can provide new insight into the state of catalysts.
Journal ArticleDOI
Transients in the formation of nanowire heterostructures.
Linus Fröberg,Brent A. Wacaser,Jakob Birkedal Wagner,Sören Jeppesen,B. Jonas Ohlsson,Knut Deppert,Lars Samuelson +6 more
TL;DR: A model that quantitatively explains the effect of seed particle reconfiguration on the growth of short InAs and InP nanowire segments is developed and with the added understanding it is able to grow short period (<10 nm) nanowires superlattices.
