eV electron spectromicroscopy using free-space light
Yves Auad, Eduardo J. C. Dias, Marcel Tencé +7
The synergy between free electrons and light has recently been leveraged to reach an impressive degree of simultaneous spatial and spectral resolution, enabling applications in mic…
Cathodoluminescence excitation spectroscopy: nanoscale imaging of excitation pathways
Nadezda Varkentina, Yves Auad, Steffi Y. Woo +9
Following the lifespan of optical excitations from their creation to decay into photons is crucial in understanding materials optical properties. Macroscopically, techniques such a…
Tailored nanoscale plasmon-enhanced vibrational electron spectroscopy
Luiz H. G. Tizei, Vahagn Mkhitaryan, Hugo Lourenço-Martins +12
Vibrational optical spectroscopies can be enhanced by surface plasmons to reach molecular-sized limits of detection and characterization. The level of enhancement strongly depends…
Enhanced Eshelby Twist on Thin Wurtzite InP Nanowires and Measurement of Local Crystal Rotation
L. H. G. Tizei, A. J. Craven, L. F. Zagonel +5
We have performed a detailed study of the lattice distortions of InP wurtzite nanowires containing an axial screw dislocation. Eshelby predicted that this kind of system should sho…
BN domains included into carbon nanotubes: role of interface
Viktoriya V. Ivanovskaya, Alberto Zobelli, Odile Stephan +2
We present a density functional theory study on the shape and arrangement of small BN domains embedded into single-walled carbon nanotubes. We show a strong tendency for the BN hex…
Quantum transport through carbon nanotubes: proximity induced and intrinsic superconductivity
A. Kasumov, M. Kociak, M. Ferrier +6
We report low temperature transport measurements on suspended single walled carbon nanotubes (both individual tubes and ropes). The technique we have developed, where tubes are sol…
