Template-Directed Growth and Assembly of Nanoscale Graphitic Carbon Structures. The various nanometre-scale forms of graphitic carbon have been strong candidates for use as novel building blocks in electronic, opto-electronic and electro-mechanical devices. However, their development has been hampered by a lack of control of the type, quality and homogeneity of structures produced by conventional methods.

The various nanometre-scale forms of graphitic carbon have been strong candidates for use as novel building blocks in electronic, opto-electronic and electro-mechanical devices. However, their development has been hampered by a lack of control of the type, quality and homogeneity of structures produced by conventional methods.
This project aims to fabricate and characterise thin films of ordered, high-quality carbon nanostructures. A novel synthesis route, involving the controlled deposition of carbon onto template substrates, is proposed. The products will be studied with near-atomic resolution to understand their formation mechanisms, and hence approach the goal of elaborating carbon-based nanodevices.
