Ultra low energy devices possible with the flick of a switch

　　Researchers at Monash University are now one step closer to providing a solution to minimising the energy wasted by modern telecommunications and computing – simply by the flick of a switch.　　Professor Michael Fuhrer, Dr Mark Edmonds and James Collins from the School of Physics and Astronomy at Monash University have, for the first time, successfully ‘switched’ a topological insulator off and on via application of an electrical field.　　This announcement is a major advancement towards the creation of a functioning topological transistor - a transistor that would burn much less energy than conventional electronics.　　“Ultra-low energy electronics, such as topological transistors, would allow computing to continue to grow without being limited by available energy. This becomes extremely important as we near the end of achievable improvements in traditional, silicon-based electronics,” said Professor Fuhrer.　　“Information and communications technology already consumes 8% of global electricity; a figure that is doubling every decade. To solve this problem, we need to develop a new type of transistor that burns less energy when it switches.　　“This discovery makes an important contribution in the direction of topological transistors that could transform the world of computation.”　　A significant proportion of the growing amount of energy used in information and communications technology is caused by transistor ‘switching’. Each time a transistor switches, a tiny amount of energy is burnt.　　“And with billions of transistors in each electronic device, switching billions of times each second, the amount of wasted energy adds up,” explained study co-author James Collins, a Monash University PhD student.　　Topological insulators are novel materials that behave as electrical insulators in their interior, but can carry a current along their edges.　　Unlike conventional electrical conductors, such topological edge paths can carry electrical current with near-zero dissipation of energy,” said lead author Dr Mark Edmonds..　　In order to be viable to the current silicon-based technology, topological transistors must operate at room temperature, without the need for expensive supercooling, and must ‘switch’ between conducting and non-conducting at a rapid rate through an electric pulse.　　“While switchable topological insulators have been proposed in theory, this is the first time that experiment has proved that a material can switch at room temperature, which is crucial for any viable replacement technology,” Dr Edmonds said.　　The research was conducted through FLEET (The Australian Research Council Centre of Excellence in Future Low-Energy Electronics Technology) – a collaboration of more than 100 researchers at seven Australian universities and 13 Australian and international science organisations.
