Numerical analysis of electric field enhancement in ZnO film with plasmonic au quantum dots

Abstract

ZnO nanostructures have generated interest for a wide range of applications due to their unique optical and electrical properties. Especially, the spontaneous polarization in the ZnO nanostructure which produces a permanent strong static electric field that can be applied to many studies. Also, their strong polarizability makes them potential candidates for many applications such as ion channel modulation, photodetector and LEDs in UV range. In this paper, the plasmonic enhancement of the induced electric field produced from ZnO nanostructures is computed by numerical analysis.
