• Scientists have developed a pioneering new technique to produce cutting—edge, versatile microchips that could revolutionise the speed, efficiency and capability of the next generation of computers.
• Researchers from the University of Exeter in the UK developed an innovative new method to engineer computer chips more easily and cheaper than conventional methods.
• The discovery could revolutionise the production of optoelectronic materials — or devices that produce, detect and control light — which are vital to the next generation of renewable energy, security and defence technologies, the researchers said.
• “The work provides a solid platform for the development of novel next—generation optoelectronic devices. Additionally, the materials and methods used are extremely promising for a wide range of further potential applications beyond the current devices.
• The team used microfluidics technology, which uses a series of minuscule channels in order to control the flow and direction of tiny amounts of fluid.
• For this research, the fluid contains graphene oxide flakes, that are mixed together in the channels, to construct the chips.
• While the graphene oxide flakes are two-dimensional the research team used a new sophisticated light—based system to drive the assembly of three—dimensional structures.
• Crucially, the research team have analysed their methodology to not only confirm the technique is successful, but also to provide a blueprint for others to use to help manufacture the chips.
