University of Wisconsin-Madison researchers have made a material that can transition from an electricity-transmitting metal to a nonconducting insulating material without changing its atomic structure. “This is quite an exciting discovery,” says Chang-Beom Eom, professor of materials science and engineering. “We’ve found a new method of electronic switching.”
The new material could lay the groundwork for ultrafast electronic devices. Metals like copper or silver conduct electricity, whereas insulators like rubber or glass do not allow current to flow...
