Newswise — Scientists have discovered that manganese coupled with sulfide, when under pressure, undergoes a surprising metamorphosis with potential uses in next-generation electronics.
A team of researchers has observed an unusual transformation in material under incredibly high pressure. Scientists captured the material, which includes manganese coupled with sulfide, changing from a soft nonconducting form to a metal and back again.
This unexpected, yet pivotal discovery means that manufacturers could see a future for this transition in the form of new components, possibly for on-off switches or conducting wires, to provide better-performing electronic devices, according to the team from the University of Nevada Las Vegas (UNLV) and the University of Rochester.
“Without the APS, we could not confirm that everything was happening in the same structure.” — Dean Smith, an assistant physicist in Argonne’s X-ray Science Division
“Much of the high-pressure research we do is fundamental research,” said Dylan Durkee, a Ph.D. student at Rochester who led the experiment while he was an undergraduate at UNLV. “However, one could imagine next-generation memory devices that take advantage of the dramatic phase transitions in materials like this one under pressure.”
The experiments were performed at the U.S. Department of Energy’s (DOE) Argonne National Laboratory using the Advanced Photon Source (APS), a DOE Office of Science user facility. The work was done at the High-Pressure...
