New p-n Junction Photodetector Using Optimized ZnO Nanorod Array

Abstract:

In this research, nanoscale spatial resolution p-n junction photodetector arrays were developed using ZnO nanorod arrays grown on p-type silicon substrates. In order to optimize the nanorod array quality, an advanced combinatorial spreadsheet approach was used to optimize the Au catalyst thickness. The crystallinity of these as-grown ZnO nanorods’ was compared to that of bulk and thin film ZnO materials.
