- •
Tapered ZnO nanorod arrays were grown by chemical bath deposition.
- •
With the coating of C QDs, the ON/OFF resistance ratio was improved over 100 times.
- •
With the coating of C QDs, the device yield was increased from 15% to 90%.
- •
The effects of C QDs were ascribed to the increased charge trapping density.
