碩士 === 國立臺南大學 === 材料科學系碩士班 === 99 === Nanoparticles have many attractive properties in optics and electronics especially when they are arranged in one dimensional array or chain structure. The structure with electron tunneling and surface plasmon resonance may provide a useful way for manufacturing nanoelectronic devices. In this study, gold nanoparticles self-assembly mechanism was utilized to construct one dimensional chain structure. Strategies of positioning the structure as well as different gold particle nanopatterns were demonstrated with methods including e-beam lithography, modification of DNA’s functional group, and static electric charge attraction. With the aid of spectral analysis and electric current measurement, the energy transport in the chain structure can be studied in depth. The research includes three parts: (a) Study of immobilization of gold nanoparticles including the influences from e-beam doses and DNA presence. (b) Construction of one dimensional Au nanoparticle chain. (c) Immobilization chain structure to a specific position. The results will help in the development of biomolecular sensors and nano-scale waveguide devices.
