Faster and smaller computer chips are on the way from the Nanyang Technological University (NTU), with researchers there at the cutting edge of materials science technology. Researchers from the School of Electrical and Electronic Engineering (EEE) has come up with a new nanotechnology process that enables smaller and faster computer chips to be built. This process is based on building computer chips made of an alloy that transmits data through light rather than today's traditional metal wiring.
