Mechanism and control of diamond and graphene-based nanostructures using direct electric-field and laser excitation

Summary

To investigate the sculpting of carbon-based structures through controlled electric field and/or laser excitation, through first-principles based calculations.

Program Type

PHD

Synopsis

Nanotechnology is currently one of the leading scientific fields, intrinsically multidisciplinary and holding the potential to lead to real-world breakthroughs in for example the areas of nanoelectronics, clean energy, and green sustainable environment. Diamond and, graphene-based structures are of high current interest due to their unique physical properties and the ability to control and modify their atomic geometry and consequently their physical and chemical properties. This project will investigate how and whether the performance of several such carbon-based structures (surfaces, sheets and quantum dots) can be enhanced and controlled by using an electric-field and/or laser excitation.  For example selective graphene oxide reduction (removing C atoms) and  the stabilising of unique morphologies on diamond surfaces  through laser irradiation.  The studies will be carried out using first-principles quantum mechanical density-functional theory calculations and involve collaboration with Macquarie University.
