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…
Observation of the Smallest Metal Nanotube with Square-cross-section
Maureen Lagos, Fernando Sato, Jeferson Bettini +3
Understanding the mechanical properties of nanoscale systems requires a range of measurement techniques and theoretical approaches to gather the relevant physical and chemical info…
Is Small Perfect? Size Limit to Defect Formation in Pyramidal Pt Nanocontacts
Varlei Rodrigues, Fernando Sato, Douglas S. Galvao +1
We report high resolution transmission electron microscopy and ab initio calculation results for the defect formation in Pt nanocontacts (NCs). Our results show that there is a siz…
Nanowires and Suspended Atom Chains from Metal alloys
J. Bettini, F. Sato, P. Z. Coura +3
We present a study of the elongation and rupture of gold-silver alloy nanowires. Atomistic details of the evolution were derived from time-resolved atomic resolution transmission e…
Evidence of spontaneous spin polarized transport in magnetic nanowires
Varlei Rodrigues, Jefferson Bettini, Paulo C. Silva +1
The exploitation of the spin in charge-based systems is opening revolutionary opportunities for device architecture. Surprisingly, room temperature electrical transport through mag…
