Polarity-dependent nonlinear optics of nanowires under electric field

Nature Communications, 2021
Finding dipole orientation of nanostructures is a challenge. Here the authors report a method to determine the sign of the polarity of a single nanowire using electric-field-modulated second-harmonic generation from surface-guided ZnO nanowire.

Electronic, Mechanical, and Piezoelectric Properties of ZnO Nanowires

, 2006
Hexagonal [0001] nonpassivated ZnO nanowires are studied with density functional calculations. The band gap and Young's modulus in nanowires which are larger than those in bulk ZnO increase along with the decrease of the radius of nanowires.
