Large anelasticity and associated energy dissipation in single-crystalline nanowires

Nature Nanotechnology, 10(8), 687–691.

By: G. Cheng n, C. Miao *, Q. Qin n, J. Li n, F. Xu n, H. Haftbaradaran *, E. Dickey n , H. Gao *, Y. Zhu n 

Contributors: G. Cheng n, C. Miao *, Q. Qin n, J. Li n, F. Xu n, H. Haftbaradaran *, E. Dickey n , H. Gao *, Y. Zhu n 

TL;DR: It is shown that single-crystalline ZnO and p-doped Si nanowires can exhibit anelastic behaviour that is up to four orders of magnitude larger than the largest anelastically observed in bulk materials, with a timescale on the order of minutes, suggesting that crystalline Nanowires with point defects are promising materials for energy damping applications.

Recoverable plasticity in penta-twinned metallic nanowires governed by dislocation nucleation and retraction

NATURE COMMUNICATIONS, 6.

By: Q. Qin n, S. Yin *, G. Cheng n, X. Li *, T. Chang n, G. Richter *, Y. Zhu n , H. Gao *

Contributors: Q. Qin n, S. Yin *, G. Cheng n, X. Li *, T. Chang n, G. Richter *, Y. Zhu n , H. Gao *

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. (via Semantic Scholar)

2014 journal article

Mechanical Properties of Silicon Carbide Nanowires: Effect of Size-Dependent Defect Density

NANO LETTERS, 14(2), 754–758.

By: G. Cheng n, T. Chang n, Q. Qin n, H. Huang* & Y. Zhu n 

Contributors: G. Cheng n, T. Chang n, Q. Qin n, H. Huang* & Y. Zhu n 

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. (via Semantic Scholar)

2012 journal article

Measuring True Young's Modulus of a Cantilevered Nanowire: Effect of Clamping on Resonance Frequency

Small, 8(16), 2571–2576.

By: Q. Qin n, F. Xu n, Y. Cao n, P. Ro n & Y. Zhu n 

Contributors: Y. Cao n, Q. Qin n, P. Ro n, F. Xu n & Y. Zhu n 

TL;DR: This work exemplifies the importance of considering the effect of clamping in measurements of Young's modulus using the resonance method, and demonstrates that the true Young'smodulus can be measured if the critical clamp size is reached. (via Semantic Scholar)
