New Research Leads To Multifunctional Spintronic Smart Sensors

Research from a team led by North Carolina State University is opening the door to smarter sensors by integrating the smart material vanadium dioxide (VO2) onto a silicon chip and using lasers to make the material magnetic. The advance paves the way for multifunctional spintronic smart sensors for use in military applications and next-generation spintronic devices.

VO2 is currently used to make infrared sensors. By integrating VO2 as a single crystal onto a silicon substrate, the researchers have made it possible to create infrared smart sensors, in which the sensor and computational function are embedded on a single chip.

This makes the sensor faster and more energy efficient, since it doesn't have to send data to another chip to be processed. Smart sensors are also lighter than conventional ones, since separate chips aren't necessary.

"For military applications, sensor technology needs to be able to sense, manipulate, and respond to data quickly - and this work achieves that," says Dr. Jay Narayan, John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and senior author of a paper describing the work.

In addition, the researchers used high-power nanosecond-pulsed laser beams to modify the VO2 and make it magnetic. This will allow the creation of spintronic smart sensors that incorporate infrared sensors and magnetic sensors on a single chip.

Spintronics refers to technologies used in solid-state devices that take advantage of the inherent spin in electrons and their related magnetic momentum. The potential advantages of spintronics include higher memory capacity, faster data transfer and more computational power on a computer chip.

The paper, "Diamagnetic to ferromagnetic switching in VO2 epitaxial thin films by nanosecond excimer laser treatment," is published online in Applied Physics Letters. Lead author of the paper is R. Molaei, a Ph.D. student at NC State. Co-authors include Dr. R. Bayati, a former Ph.D. student at NC State who now works at Intel Corporation; Dr. S. Nori, a postdoctoral researcher at NC State; Dr. D. Kumar, of North Carolina A&T University; and Dr. J.T. Prater of the Army Research Office, who is also an adjunct professor at NC State. The work was supported by the National Science Foundation, under grants DMR-1304607 and DMR-0803663.

Ballistic transport in graphene suggests new type of electronic device
Atlanta GA (SPX) Feb 12, 2014
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature - a property known as ballistic transport. Research reported this week shows that electrical resistance in nanoribbons of epitaxial graphene changes in discrete steps followi ... read more
