effects of piezopotential spatial distribution on local contact dictated transport property of zno micro nanowires
Applied Physics Letters, 2010Co-Authors: Yan Zhang, Youfan Hu, Shu Xiang, Zhong Lin WangAbstract:We present a study on the effect of Deformation induced piezoelectric potential (piezopotential) in a ZnO micro/nanowire on its electrical transport properties by choosing different contacting locations on the wire to form a metal-ZnO contact. When a ZnO wire is under Nonuniform Deformation, the local piezopotential distribution at different positions shows significant effect on and distinct trend of variation in the charge carrier transport characteristic. This study has a broad impact on understanding the characteristics of piezotronic devices based on nanowires of wurtzite materials by controlling local contact position and contact size.

Numerical analysis of strain path dependency in FCC metals
Computational Mechanics, 2008Co-Authors: E. M. Viatkina, W. A. M. Brekelmans, M. G. D. GeersAbstract:Strain path dependency in FCC metals is often associated with the anisotropy induced by the dislocation cell structure in deformed metals. In this paper, the mechanical behaviour of metals under various Nonuniform Deformation paths is studied with the use of a recently developed dislocation cell structure model. It is shown that this model correctly captures the essential features of strain path change effects for moderate strain path changes, i.e. the anisotropy and the dependency on the amount of prestrain. Next, a numerical analysis is performed to assess the micromechanical origin of the modified reloading yield stress and the transient hardening after strain path changes. The separate influence of anisotropic effects due to the cell structure morphology and residual internal stresses are thereby addressed and illustrated. The transient hardening behaviour after a strain path change is related to the adjustment of the internal stresses to the new loading. Results obtained are consistent with related experimental findings reported in literature.
