Copper at risk from new chip material
A team of researchers has developed a new type of nanowire made from niobium arsenide (NbAs), which serves as a potential alternative to copper for connecting components in computer chips. This material possesses a unique property: its electrical conductivity improves as its size is reduced, unlike copper, whose electrical resistance increases when its dimensions are scaled down to the nanoscale. This achievement is significant because it addresses the challenges of electrical resistance faced when miniaturizing modern chips, thereby enhancing processor performance and increasing energy efficiency. The wires were fabricated using a mechanical thermal nanostructuring technique, resulting in a diameter of about 10 nanometers, with future possibilities for integration into silicon chips. This could pave the way for the development of faster, more efficient electronic devices. The study's findings were published in the journal *Science* and suggest that it may be possible to surpass copper’s physical limitations to develop a new generation of electronic chips that boost computing speed and energy efficiency.
