Functional oxide thin films create new field of oxide electronics
Date:3/7/2012

Researchers from North Carolina State University have developed the first functional oxide thin films that can be used efficiently in electronics, opening the door to an array of new high-power devices and smart sensors. This is the first time that researchers have been able to produce positively charged (p-type) conduction and negatively charged (n-type) conduction in a single oxide material, launching a new era in oxide electronics.

To make functional electronic devices, you need materials with a "p-n junction," where the positively charged and negatively charged materials meet. Solid state silicon electronics achieved this decades ago, but are limited by the amount of power and temperature they can handle. Oxide materials are an attractive alternative to silicon because they can handle more power.

However, attempts to pair different p-type and n-type oxide materials previously ran into problems at the interface of the two materials the p-n junction was always inefficient.

"We avoided this problem by using the same material for p- and n-type conduction," says Dr. Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and co-author of a paper describing the research. "This is a new era in oxide electronics."

Specifically, Narayan's team used lasers to create positively charged nickel oxide (NiO) thin films, then converted the top layer of those films to n-type. Because they could control the thickness of the n-layer, the researchers were able to control the depth and characteristics of the p-n junction. "This spatial and temporal selectivity provides unprecedented control to 'write' p-n junctions by laser beams and create ultra high-density device features for oxide electronics," Narayan says.

By enabling the development of oxide electronics, the research allows for the creation of a host of new technologies in a wide array of fields. For example, because oxides
