We are on the cusp of a materials revolution – in electronics, health care, and avionics – says guest engineer-scientist Eric Pop. For instance, silicon and copper have served electronics admirably for decades, he says, but at the nanoscale, better materials will be needed. Atomically thin two-dimensional semiconductors (like molybdenum disulfide) and topological semimetals (like niobium phosphide) are two candidates, but with AI tools to design new materials, the future is going to be really interesting, Pop tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
