Linear defects in crystalline materials, known as dislocations, are central to the
understanding of plastic deformation and mechanical strength, as well as control of …

We demonstrate strain-rate sensitivity emerging in single-crystalline Cu nanopillars with
diameters ranging from 75 up to 500nm through uniaxial deformation experiments …

The nature of dislocation sources in small-scale metals is critical to understanding and
building models of size-dependent crystalline strength at the nanoscale. Pre-existing …

The finite-temperature mechanical strength of nanoscale pristine metals at laboratory strain
rates may be controlled by surface dislocation nucleation, which was hypothesized to be …

Dislocations are common defects in solids, yet all crystals begin as dislocation-free nuclei.
The mechanisms by which dislocations form during early growth are poorly understood …

Abstract Nanometre-scale contact experiments,,,,, and simulations,,, demonstrate the
potential to probe incipient plasticity—the onset of permanent deformation—in crystals. Such …

Nanoindentation has become ubiquitous for the measurement of mechanical properties at
ever-decreasing scales of interest, including some studies that have explored the atomic …

Abstract 'Smaller is stronger'does not hold true only for nanocrystalline materials but also for
single crystals,,,. It is argued that this effect is caused by geometrical constraints on the …

Dislocation nucleation is essential to the plastic deformation of small-volume crystalline
solids. The free surface may act as an effective source of dislocations to initiate and sustain …

The formation of dislocations is central to our understanding of yield, work hardening,
fracture, and fatigue of crystalline materials. While dislocations have been studied …
