"chip's substrate responds to changes in electricity... semiconductor material vanadium dioxide behaves similarly to its substrate titanium dioxide when semiconductor switches between insulator (stops electricity) and metal (letting electricity flow, film channel bulges) ... high-temperature superconductivity and enhanced magnetic properties... oxygen atom vacancies hold charge of 2 electrons, released when switches from insulator to metal... faster, more efficient electronics, neuromorphic computing"
