In situ bending tests and dynamic modeling simulations are for the first time revealing the mechanical behavior of copper nanowires (NW) with radially grown fivefold twin structures on the atomic scale. Combining the simulations with the experimental results it is shown that both the twin boundaries (TBs) and the twin center act as dislocation sources. TB migration and L‐locks are readily observed...
Single‐crystalline ZnO nanowire bundles have been synthesized in large‐scale by an improved microemulsion method in the presence of excessive hydrate hydrazine and dodecyl benzene sulfonic acid sodium salt (DBS) in xylene. The product is characterized using X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high‐resolution transmission electron...
Local-oriented single-crystalline ZnO nanowires have been synthesized in large scale by a simple microemulsion method in the presence of sulfonate-polystyrene (S-PS) and dodecyl benzene sulfonic acid sodium salt (DBS). The as-prepared product is characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), infrared...
The wurtzite ZnO material exhibits excellent piezoelectric property along the [0001]-direction because of the noncentrosymmetric structure. As a typical II-VI wide band gap compound, it has been long studied as a piezoelectric material. Here we review the previous theoretical and experimental researches on the piezoelectric properties of ZnO and its nanostructures. Some practical applications in nanodevices...
