The study of materials at extreme pressures is important and interesting from both a technological and a fundamental perspective. This project will significantly advance the understanding of how semiconductors react to high-pressure environments by exploiting new and innovative approaches to both the application of the extreme pressure and the in-situ measurement of the resultant structures. It will establish a comprehensive understanding of the deformation behaviour of semiconductors that will be essential in the search for advanced materials with entirely new properties that may be useful in semiconducting device applications.Read moreRead less

The effect of stress on the production and evolution of defects in ion-implanted silicon. This project aims to improve the reliability of semiconductor devices by understanding how stresses created within the device during processing affect the formation and migration of defects, and by using this information to improve device modelling and process simulation.
Porosity in Si, Ge and the Si(x)Ge(1-x) alloys induced by ion irradiation. Ion beam methods will be used to form porous layers in Si, Ge and their alloys with a range of technological applications. The distributions of pore size and shape will be characterised with laboratory and synchrotron-based analytical techniques including a 3D reconstruction of the irradiation-induced porous structure.

Towards phase, composition and homogeneity control in ternary nanowires. Semiconductor nanowires have enormous potential for large scale industry manufacturing as each individual nanowire represents one device. The aim of this project is the catalyst-free growth of ternary nanowires with control over structure, composition and homogeneity within the wire.

Semiconductor nanowires have enormous potential for large scale industry manufacturing as each individual nanowire represents one device. The aim of this project is the catalyst-free growth of ternary nanowires with control over structure, composition and homogeneity within the wire. Detailed electron microscopy analyses are essential to reconstruct a three-dimensional view of the nanowires and understand the growth mechanism at work. These structural characteristics determine the optical properties. It is expected that precise control over growth will allow the emission wavelength of the nanowires to be tuned and allow their use in optoelectronic device structures. Two innovative techniques are proposed using strain and patterned substrates for ternary nanowire growth.Read moreRead less
