Description

Self-assembled ZnO nanocrystals were fabricated by using a RF-magnetron sputtering system. The average diameters of the nanocrystals with different deposition times were roughly 41 nm and 62 nm. The nanocrystals had a preferred orientation to c-axis in the surface-normal direction, but were disordered in the in-plane direction. Photoluminescence measurements of the nanocrystals revealed an intense UV peak at 3.380 eV at 15 K (with a width of 65 meV), which corresponds to the free exciton energy.
