In Situ Nano-thermomechanical Experiment Reveals Brittle to Ductile Transition in Silicon Nanowires
NANO LETTERS, 19(8), 5327–5334.
author keywords: Brittle to ductile transition; dislocation; plasticity; silicon nanowire; in situ TEM
TL;DR:
In situ high resolution TEM imaging and atomistic reaction pathway modeling reveal that the unconventional ½〈110〉{001} dislocations become highly active with increasing temperature and thus play a critical role in the formation of deformation bands, leading to transition from brittle fracture to dislocation-mediated failure in Si nanowires at elevated temperatures.

2017 journal article
Anomalous Tensile Detwinning in Twinned Nanowires
PHYSICAL REVIEW LETTERS, 19(25).
TL;DR:
Using quantitative in situ transmission electron microscopy based nanomechanical testing and molecular dynamics simulations, a transition of the deformation mechanism from localized dislocation slip to delocalized plasticity via an anomalous tensile detwinning mechanism in bitwinned metallic NWs is reported.

2015 journal article
Recoverable plasticity in penta-twinned metallic nanowires governed by dislocation nucleation and retraction
NATURE COMMUNICATIONS, 6.
TL;DR:
A dislocation-mediated, time-dependent and fully reversible plastic behaviour in penta-twinned silver nanowires is reported, which originates from the surface nucleation, propagation and retraction of partial dislocations.

2014 journal article
Mechanical Properties of Silicon Carbide Nanowires: Effect of Size-Dependent Defect Density
NANO LETTERS, 14(2), 754–758.
author keywords: Size effect; ultrahigh strength; in situ tensile testing; brittle fracture; nanomechanics
TL;DR:
The SiC NWs are found to deform linear elastically until brittle fracture, and their fracture origin is identified in the 3C structures with inclined SFs, rather than the highly defective structures.
