My past and present research has been revolving around the investigation of quantum effects. I have studied single crystal, high temperature superconductors in high magnetic fields at low temperatures. In the field of elementary particle physics, I have been involved in the first experimental observation of quantization of neutron energy eigen states due to the presence of the earth's gravitational field.
My present area of research is aimed at the study of quantum transport phenomena in semiconductor nanostructures created by scanning tunneling microscopy (STM). This involves the fabrication of buried Si:P devices in ultra high vacuum using a combination of STM-based hydrogen lithography, scanning electron microscopy and molecular beam epitaxy. By using a novel registration technique, it is now possible to align macroscopic contacts to buried STM-fabricated devices ex-situ using conventional optical lithography. The characterisation of their electrical properties at low temperatures and high magnetic fields provides vital information for the fabrication of devices with feature sizes approaching the quantum limit.
The suitability of this approach for the fabrication of atomic scale devices make this method a suitable candidate for the fabrication of a solid state quantum computer that exploits the nuclear spin of single atoms to act as quantum bits (qubits).
