Recent advances in new materials engineering holds a promise of surmounting the miniaturization limits of silicon technology by exploiting the spin of electrons in semiconductors. Spin transistor is among a number of nanoscale devices that may revolutionize telecommunications, computing and daily life. Current transistors are electronic circuits that make up most semiconductors; an international market will grow to US$1000bn per year in 2013. In a few years, the spin transistor will be on par with electronics. Success of this program will facilitate the development of spintronic materials and technologies, and also generated patents and intellectual properties, thus resulting in revenue for Australia through their commercialisations.Read moreRead less
