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…
Nanosized precipitates in H13 tool steel low temperature plasma nitriding
L. F. Zagonel, J. Bettini, R. L. O. Basso +4
A comprehensive study of pulsed nitriding in AISI H13 tool steel at low temperature (400°C) is reported for several durations. X-ray diffraction results reveal that a nitrogen enri…
On the Formation of Copper Linear Atomic Suspended Chains
F. Sato, A. S. Moreira, J. Bettini +4
We report high resolution transmission electron microscopy and classical molecular dynamics simulation results of mechanically stretching copper nanowires conducting to linear atom…
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…
Quantum Conductance in Silver Nanowires: correlation between atomic structure and transport properties
V. Rodrigues, J. Bettini, A. R. Rocha +2
We have analyzed the atomic arrangements and quantum conductance of silver nanowires generated by mechanical elongation. The surface properties of Ag induce unexpected structural p…
