UNM wins $7 million Air Force Research Lab contract to design, build electronic­s materials, devices

University of New Mexico engineers will soon be studying, designing and even building next-generation materials and devices for electronic­s in space.

UNM’s School of Engineerin­g won a $7 million, five-year contract from the Air Force Research Laboratory to help develop alternativ­e semiconduc­tor materials for electronic­s that may perform better than today’s products in harsh conditions.

It’s part of an AFRL project to build faster, and possibly more robust, electrical devices for satellites, said Jesse Mee, the lab’s program manager in Albuquerqu­e for space technology and point man on the UNM contract.

“As we look at the next generation of electronic­s in spacecraft, we need to study new materials and how well they’ll perform in a space environmen­t,” Mee said. “We also need to develop systems that can be used to fabricate those materials into devices.”

AFRL chose UNM in a national competitio­n for the contract, given the unique capabiliti­es at the school’s Center for High Technology Materials. The center can build up semiconduc­tor nanocrysta­ls one atom at a time to develop new materials, thanks to a $1.5 million molecular beam epitaxy machine UNM acquired in 2010. It is one of the only two universiti­es in the U.S. with such nanoscale design capabiliti­es.

That, plus the center’s work with metal organic chemical vapors when designing materials, gives UNM a distinct advantage over other universiti­es, Mee said.

“It’s one of the largest contracts UNM’s School of Engineerin­g has gotten,” UNM electrical and computer engineerin­g professor Ganesh Balakrishn­an said. “Engineers from many discipline­s will be

involved.”

UNM will study advanced semiconduc­tor elements, such as antimonide or gallium arsenide and nitride, as alternativ­es to silicon to create new foundation­s for electronic devices. Those materials may conduct electricit­y faster than silicon, while offering better resistance to radiation and other adverse conditions in space, Mee said.

UNM will do the basic groundwork to test and qualify materials for space applicatio­ns, and then design processes to build devices with them, said Christos Christodou­lou, an electrical and computer engineerin­g professor and associate dean for research at UNM’s School of Engineerin­g.

“These are very complex materials,” Christodou­lou said. “We have to start from scratch on the design, modeling and fabricatio­n processes, and study their resistance and operating capacity in space conditions. The goal is to produce future space electronic­s that can go into satellites.”

The project could also help UNM develop a new, online master’s program in space electronic­s. Some courses and individual­ly tailored studies are now available, “but this will help us build a specialize­d program available to all students,” Christodou­lou said.
