Preparation and study of amorphous GaN
This project has been granted NERF funding of about 1 $200k p.a. ($90k to VUW). It is being carried out in collaboration with A. Bittar at IRL, Roger Reeves and Steve Durbin at the U. of Canterbury, Andreas Markwitz at IGNS, Jim Metson at U. Auckland and several groups overseas. The material is of interest for its electro-optic and spintronic promise.
Vortices in superconductors
This is an ongoing project started in 1993. It has attracted support from the PGSF ($300 000, 1994-7), the Marsden Fund ($300 000, 1999-2002) and the US-NZ Cooperation Agreement ($5 000, 1998).
Properties of the cuprate superconductors
This VUW-IRL collaboration has been running continuously since the materials were discovered in 1987. The VUW research has been supported by the PGSF ($300k, 1994-7), the Marsden Fund ($70k, 1999-2002) and by the support of numerous students by IRL (PGSF funds). The VUW work has focussed on Raman spectroscopy and (in collaboration with Alan Kaiser) electron transport studies.
Properties of Strongly Correlated Transition Metal Oxides
This is a collaboration between IRL and VUW in which the IRL effort is supported by Marsden funds. That source pays two students and supports the direct costs of the research of one PhD student (approximately $400k, 1998-2006).
Optical and thermal properties of sea ice
This is a VUW programme within a large VUW, Otago U., Massey U., U. of Auckland, IRL collaboration studying a wide range of physical sea ice problems of relevance to climate and Southern Ocean biological communities. The VUW component has attracted PGSF support amounting to about $350k since 1996. We work in a close collaboration with scientists at the Geophysical Institute, University of Alaska, Fairbanks. Visit the Sea Ice Research at VUW for more information.
