After semiconductors, semimetals might be the next big thing as the tech industry looks for a replacement for ubiquitous copper

SMRTR summary

Researchers at Stanford University have discovered that niobium phosphide, a semimetal, outperforms copper in conducting electricity at nanometer scales. This breakthrough could lead to more energy-efficient electronics, as niobium phosphide's resistivity decreases with thickness, reaching one-sixth of copper's at similar scales, and it's compatible with existing semiconductor technologies.
