High Precision Orientation Mapping from 4D-STEM Precession Electron Diffraction data through Quantitative Analysis of Diffracted Intensities
Leonardo Corrêa, Eduardo Ortega, Arturo Ponce +2
The association of scanning transmission electron microscopy (STEM) and the detection of a diffraction pattern at each probe position (so-called 4D-STEM) represents one of the most…
Controlling Multipolar Surface Plasmon Excitation through the Azimuthal Phase Structure of Electron Vortex Beams
Daniel Ugarte, Caterina Ducati
We have theoretically studied how the azimuthal phase structure of an electron vortex beam excites surface plasmons on metal particles of different geometries as observed in electr…
Surface Effects on the Mechanical Elongation of AuCu Nanowires: De-alloying and the Formation of Mixed Suspended Atomic Chains
M. J. Lagos, P. A. S. Autreto, J. Bettini +4
We report here an atomistic study of the mechanical deformation of AuxCu(1-x) atomic-size wires (NWs) by means of high resolution transmission electron microscopy (HRTEM) experimen…
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…
Correlation between Quantum Conductance and Atomic Arrangement of Silver Atomic-Size Nanowires
M. J. Lagos, P. A. S. Autreto, D. S. Galvao +1
We have studied the effect of thermal effects on the structural and transport response of Ag atomic-size nanowires generated by mechanical elongation. Our study involves both time-…
Mechanical Deformation of Nanoscale Metal Rods: When size and shape matters
Maureen J. Lagos, Fernando Sato, Douglas S. Galvao +1
Understanding nanomechanical response of materials represents a scientific challenge. Here, we have used in-situ electron microscopy to reveal drastic for the first time changes of…
