Vibration of Piezoelectric ZnO-SWCNT Nanowires [PDF]

Nanomaterials, 2016
A hybrid nanowire (HNW) was constructed by coating a single-wall carbon nanotube (SWCNT) with piezoelectric zinc oxide (ZnO). The two components of the HNW interact with each other via the van der Waals (vdW) force. This paper aims to study the effect of the piezoelectricity in the ZnO layer and the inter-phase vdW interaction on the fundamental ...

Improved Optical Property and Lasing of ZnO Nanowires by Ar Plasma Treatment

Nanoscale Research Letters, 2019
ZnO nanowires play a very important role in optoelectronic devices due to the wide bandgap and high exciton binding energy. However, for one-dimensional nanowire, due to the large surface to volume ratio, surface traps and surface adsorbed species acts ...
