➀ Researchers at Stanford University have demonstrated that niobium phosphide films, just a few atoms thick, can conduct electricity more efficiently than copper. This is due to the material's unique surface conduction properties, which enhance its conductivity even as the film thickness decreases. ➁ The films can be fabricated at temperatures compatible with modern chip manufacturing processes, potentially leading to more powerful and energy-efficient electronics. ➂ The research could pave the way for exploring other topological semimetals as potential conductors in future electronics.
