Defect Engineering of 2D Materials

This project investigates the structure and density of defects created in 2D materials by energetic ion irradiation, and their effect on the the physical properties of these materials.

Solid state synapses and neurons - memristive devices for neuromorphic computing

Interest in neuromorphic computing has led to interest in an excting new range of of solid-state neurons and synapses based on non-volatile resistive-switching and volatile threshold-switching in metal-oxide thin films.  This project explores the operation and functionality of these new devices with an emphasis on understanding the underlying mechanisms and materials physics.

Ultra-low contact resistance next generation semiconductor devices

Contact resistance is becoming a major limitation to device performance and new strategies are required to meet the needs of next-generation devices.  Existing contacts typically exploit the thermal and chemical stability of silicide/Si interfaces and take the form of a metal/silicide/Si heterostructure (e.g. W/TiN/TiSi2/Si), with the contact resistance dominated by the silicide/Si interface. The contact resistance of this interface is limited by the doping concentration in the Si substrate and the Schottky barrier height (SBH) of the heterojunction.  However, doping concentrations already exceed equilibrium solid solubility limits and further increases achieve only minor improvements.  Instead, any further reduction in contact resistivity relies on reducing the SBH.  This project will explore methods for controlling the SBH and develop device structures for measuring ultra-low contact resistivities.
