In a pivotal breakthrough researchers find ways to use Zinc Oxide for the construction of semi-conductors, opening the door to more advanced technologies
"(Phys.org) —Researchers from North Carolina State University have solved a long-standing materials science problem, making it possible to create new semiconductor devices using zinc oxide (ZnO) – including efficient ultraviolet (UV) lasers and LED devices for use in sensors and drinking water treatment, as well as new ferromagnetic devices.
"The challenge of using ZnO to make these devices has stumped researchers for a long time, and we've developed a solution that uses some very common elements: nitrogen, hydrogen and oxygen," says Dr. Lew Reynolds, co-author of a paper describing the research and a teaching associate professor of materials science and engineering at NC State. "We've shown that it can be done, and how it can be done – and that opens the door to a suite of new UV laser and LED technologies," says Dr. Judith Reynolds, a research scientist at NC State and lead author of the paper."
