Indium Nitride Emerges. Over twenty years ago the world’s purest indium nitride was grown at Macquarie University by Trevor Tansley and Cathey Foley. This record has never been equaled. Now after more than two decades in the wilderness, international interest in indium nitride is being fueled by the potential to create higher mobility (faster) high power nitride based transistor devices. The old apparatus used to create the highest mobility (fastest) indium nitride ever grown is still in existence at Macquarie University, and has recently been upgraded to attempt another Macquarie led assault on the old record. The hope here is to understand the film growth parameters to the point where high mobility material can be routinely grown at Macquarie. If this can be achieved then the University will begin to supply this material to research groups around the world on a commercial basis.
We graciously acknowledge the funding recently received by us from NICOP in partnership with the U.S. Office of Naval Research. In particular we acknowledge Dr Colin Wood and Dr Jaime Freitas Jr. for their roles in this support. These funds have been instrumental in allowing the update of our low temperature metalorganic CVD growth system, and has allowed us to greatly forward our understanding of low temperature growth processes. The U.S. Office of Naval Research also provides a useful on-line semiconductor based facility - the U.S. National Compound Semiconductor Roadmap.
Funding from the Australian Institute of Nuclear Science and Engineering (AINSE) has allowed us access to a Cameca 5f SIMS system for the analysis of the composition of our nitride films. Through AINSE we also have access to a DLTS facility that allows us to probe the electronic defect structure of our films.
Not least of all in this list we must thank Macquarie University, the Division of ICS and the Physics Department for their continuing support. Dr K. S. A. Butcher is particularly thankful for the support of a Macquarie University Research Fellowship (MURF).
