Exploring novel X-ray scanning trajectories

The first 3D X-ray microscopes used viewing angles evenly spaced in a full 360 degrees around the sample. Recent innovations have freed us from this constraint: the microscopes at the ANU CTLab can utilise ever stranger and more innovative scanning patterns. However, this new freedom is not well explored.

X-ray scatter in 3D microscopes

X-ray scatter is most significant when imaging very dense/large samples: e.g. metal parts, large 3D printed components, or samples imaged on the CTLab's new "whole core" scanner. The student will develop methods to correct for its effects, both in-hardware (i.e. at the microscope) and in-software (i.e. image analysis).

Wave dispersion in stringed instruments: What makes tuning a piano so hard?

Ideal strings have wave speeds that are identical for all frequencies.  In real life, strings have some stiffness that makes higher frequency waves are faster.  This means building and tuning some stringed instruments, like pianos, is very tricky. This project aims to accurately measure wave speeds on piano strings.

Achieving ultra-low contact resistance for 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.
