Postgraduate Research

Carbon based Nano-electronic and Spintronic Device Applications Project: New Research Directions With the support of South African government funding agencies (NRF) I have been successful in establishing a research group, the Nano-Scale Transport Physics Laboratory (NSTPL) which has facilities for the nanoelectronic device fabrication and study of quantum transport in nano-materials at low temperatures (300 milli Kelvin), high magnetic fields (12 Tesla) and high frequencies (10 MHz - 65GHz). All of our works during 2012-2015 were performed in the NSTPL have been successful in the following areas:  http://www.wits.ac.za/nstpl/.

• Disorder induced superconductivity in diamond films both experimentally and theoretically [several publications].
• Quantum transport in nanotube and silicon nanowire-based devices created by e-beam lithography.
• Device (waveguides) fabrication using nano-manipulators from graphite flakes.
• High frequency response measurements up to 67 GHz in nanotube devices at 4 K.
• Theoretical model explaining the quantum transport in carbon films: Superlattice structures.
