| Summary: | 碩士 === 國立臺南大學 === 材料科學系碩士班 === 100 === In this study, we used Au nano-particle as a building block for making a nano-field-effect-transistor. This is due to Au nano-particle’s special properties such as electron tunneling and plasmon resonance etc.
At first, self-assembled Au nano-particle chains were formed on a liquid surface. We developed a method to translate the particle chains onto the silicon substrate and connected them with a pair of electrodes for the electrical current measurement. Secondly, Zinc oxide nano-particles were introduced to bridging the Au particles in order to transport electrons which can be controlled with the external field and light. Lastly, e-beam lithography was employed to make a well ordered one dimensional Au particle array to replace the self-assembled particle chain for improving the current stability.
The result showed that the assembly of one dimensional Au particle array with ZnO nano-particles displayed well defined field-effect-transistor IV characteristics and sensitive response to the UV light. The method we develop in this study provides a simple direct way to construct a photo-electronic nano-device at a specified location.
