This project focuses on the synthesis and attachment of metal nanoparticles to Au and GaAs surfaces using a combination of chemical self-assembly and scanned probe lithography. In this project self-assembled monolayers (SAMs) of alkanethiols and dithiols were prepared on Au and GaAs surfaces. There chemical assembly was investigated using a combination of Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The surface morphology and nanopatterning of these SAMs was investigated using atomic force microscopy. Lastly, as the final goal of the project was to create single electron tunneling devices by attaching metal nanoparticles to these surfaces, Au nanoparticles of varying sizes ranging from ca 2 – 12 nm were synthesized.
