Abstract:
In this presentation, a monolayer of silver nanoplate is introduced as an epitaxial template and doping source for vertically aligned p-type ZnO nanorods. Silver nanoplates were synthesized through room temperature polyol process and the monolayer consisting of the nanoplates was assembled on the water surface to be scooped on a substrate. For the growth of ZnO nanorods, ammonium hydroxide was used as a mineralizer under the hydrothermal process. During the hydrothermal process, the silver nanoplate was dissolved to generate silver ions in the reaction solution. The silver ions can be doped in the wurzite structure of ZnO and also the (111) plane of silver nanoplate can be the epitaxial template for the (0001) plane of ZnO. Therefore, using this idea, Ag-doped p-type ZnO nanorods were successfully grown on the substrate, which can be an electrode or n-type semiconductor for the device application. Experimentally, the process to synthesize silver nanoplate was optimized to get high yield for nanoplate and doping concentration was modulated by changing the number of the monolayer on a substrate. To show the capability of this idea, Schottky and p-n diodes were fabricated and flexible organic-inorganic hybrid lighting emitting diode was also fabricated.
