    Abstract

    The very successful First International Workshop on Indium Nitride was held at the Esplanade Hotel in Fremantle Australia 16–20 November 2003 with W.J. Schaff and myself (K.S.A. Butcher) as co-chairs. The workshop was organised in the highly productive format preferred by Dr. Colin Wood, who, with his superiors at the US Office of Naval Research, championed its sponsorship here in Australia. Over the last two years there has been a growing recognition of the potential of indium nitride. This event represented the first international gathering solely devoted to the study of this material, and heralds the results of major research efforts in the area.

    The event attendees widely commented on the fact that they learned a considerable amount about InN at the workshop. Not surprising given the range of expertise gathered together for this event. In particular the possibility of a ∼1.2 eV bandgap was strongly re-established; a 1.4 eV surface bandgap was measured; it was shown that oxygen alloying was insufficient to account for the ∼2 eV bandgap observed for some material; indium rich regions were implicated in the ∼0.7 eV absorption and emission features; while other results seemed to bring the bandgap of InN down to a value as low as 0.6 eV. Carrier dynamics and lifetime measurements are featured in this proceedings. Ion based defect studies indicate indium vacancies/nitrogen rich regions near the substrate interface. Very high-quality CVD material has begun to appear, with extremely low compensation levels, as mechanisms for low temperature growth are improved. Results on the piezoelectric properties, InN spintronic alloys, InN-based nanowires and quantum dots were all reported.

    The InN workshop was indeed a highly successful event, and a second workshop is being planned for January 2005. We would like to acknowledge the support of the other sponsors of the workshop including the US Office of Naval Research Global, the Air Force Office of Scientific Research, the Asian Office of Aerospace Research and Development, the Australian Nuclear Science and Technology Organisation, and Macquarie University, its Division of Information and Communication Sciences, and its Physics Department. Finally, our thanks to Shari Allwood of Allwood Associates who organised the venue and social programmes and without whom this workshop could not have happened and our thanks to the Journal of Crystal Growth and Elsevier Publishing for their great patience.
