2. 1. Zinc Oxide Bulk and Nanorods

   Author : Peter Klason; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc oxide; Schottky contact; buckling; annealing; semiconductor growth; ion implantation; photoluminescence; nanorods;

   Abstract : Zinc Oxide (ZnO) has many promising properties for optoelectronics, sensor applications, transparent electronics etc. To mention a few, ZnO has a large exciton binding energy (60 meV at room temperature) and a direct wide bandgap energy of 3.37 eV. In addition, ZnO is piezoelectric and shows more resistance to radiation damage than Si and GaN. READ MORE
