To try and answer this very question, the First International Workshop on Indium Nitride met at the Esplanade Hotel in Fremantle Western Australia from 16th to 20th November 2003. Other device and material related properties were also addressed, but the question that had long been raging was about the material's band-gap. It had long been established as being 1.89 eV , but had recently been 'announced', in various popular magazines, to actually be closer to 0.7 eV. So what is the band-gap? Why is there such a large variation observed for such a fundamental property? Why on earth is anyone interested in indium nitride anyway? And how did a workshop heavily sponsored by U.S. military funding (U.S. Office of Naval Research Global, the Office of Naval Research, the Air Force Office of Scientific Research, and the Asian Office of Aerospace Research and Development) end up being held in Australia?
