Abstract Details

2006, Master of Science, Miami University, Physics.
Molecular electronics is an emerging field that makes it possible to build electronic devices with single molecules as their active element. The conductivity of single molecules can be manipulated to perform functions similar to present-day bulk electronic devices. These single molecules, with a size of few nano-meters, can be designed and chemically synthesized with tailored electronic structures. This thesis focuses on the design, fabrication and measurement of nanogap electronic devices. The enabling device to study the conductivity of dimetal paddlewheel inorganic complexes, using electrode pairs with nanometer separation is fabricated. A study of these inorganic complexes would provide more versatile opportunities for tailoring electron transport properties. The molecular complex and its electron transport mechanism are discussed and a detailed description of the fabrication of the nano-gap electrode with a controlled gap size is provided. Electron beam lithography fabrication techniques are discussed in detail. A reliable method to fabricate a controlled nanogap with electrodeposition and electromigration is demonstrated. The results of I-V curves of gaps are used to estimate the nanogap dimensions via comparison to tunneling current theory.
