Improved characteristics of near-band-edge and deep-level emissions from ZnO nanorod arrays by atomic-layer-deposited Al<sub>2</sub>O<sub>3 </sub>and ZnO shell layers

<p>Abstract</p> <p>We report on the characteristics of near-band-edge (NBE) emission and deep-level band from ZnO/Al<sub>2</sub>O<sub>3 </sub>and ZnO/ZnO core-shell nanorod arrays (NRAs). Vertically aligned ZnO NRAs were synthesized by an aqueous chemical me...
