Researchers from Purdue and Harvard universities have created a new type of transistor made from a material that could replace silicon and have a 3-D structure instead of conventional flat computer chips.
The approach could enable engineers to build faster, more compact and efficient integrated circuits and lighter laptops that generate less heat than today's. The transistors contain tiny nanowires made not of silicon, like conventional transistors, but from a material called indium-gallium-arsenide.
