ASU physicist Robert Nemanich harnesses power of diamonds

Robert Nemanich's diamond-powered transistor projects total $3 million for ASU.

Newly selected Regents' Professor creates diamond wafers for high-power electronics to improve efficiency, functioning

ASU Physics Professor Robert Nemanich doesn’t have 99 bottles of beer on the wall; he has 75 bottles of champagne on the top of his desk.

It’s a tradition that comes from commencement whenever one of his graduate students gets their degree. So far he has seen 53 students receive their PhDs and 22 obtain their masters under his tutelage.

“It’s good to punctuate your life whenever there’s a big accomplishment,” Nemanich said. “If you don’t celebrate those victories, then it’s just another day.”

Recently, the university toasted Nemanich by naming him as one of threeASU scholars Anne Stone and Paul Westerhoff are the other two Regents’ Professors for 2016-2017. Regents' Professors for the 2016-17 academic year.

Regents’ Professor is the highest faculty honor and is conferred on full professors who have made remarkable achievements that have brought them national attention and international distinction.

“Professor Nemanich is an outstanding classroom instructor and has also been a pioneer in the development of online courses,” said Peter A. Bennett, professor and chair in ASU’s Department of Physics. He added that another form of teaching is in the mentoring of research personnel and that “here Professor Nemanich also shines.”

That summation is fitting given that Nemanich’s work focuses on the creation and use of diamond wafers instead of silicon wafers for high-power electronics, providing improved efficiency and ability to function in high-temperature applications.

“These wafers are small, lightweight and conduct heat away rather than overheating,” Nemanich said. The diamond wafers can be used for high-power grids, electronic cars, jet engines and trains.

The electronics are made in an ASU lab by electrically conducting diamond layers on the wafers. The lab-grown diamonds are fabricated at high pressure, or by plasma growth as opposed to being mined in the ground. The materials could be coal or high-purity gas sources.

Nemanich’s research projects for diamond-powered transistors have totaled close to $3 million for ASU. He has also presented more than 200 invited lectures and published more than 400 research papers, which have been cited in scientific literature more than 22,000 times, according to the university.

“His pioneering contributions have had remarkable impact in interdisciplinary materials physics,” said ASU physics and Regents’ Professor David Smith. “His research is highly regarded at both national and international levels.”

Nemanich has served as president of the Materials Research Society, one of the largest scientific societies in this country, as well as president of the International Union of Materials Research Society.

He also had a highly distinguished record of service as physics department chair at ASU from 2006 to 2013.

Accolades aside, for Nemanich the great joy of his work is forging lasting relationships with his physics, electrical engineering and material science students.

“He seems to have an intuitive understanding how to help us be successful and tailors his own method of teaching and motivating to each of us,” said Brianna Eller, who received her PhD in physics from Nemanich in 2015. “I hope that I have learned how to be a better mentor as his student in addition to learning from his wealth of knowledge.”

Nemanich said a good portion of his knowledge comes from students.

“The game is who learns more from who?” Nemanich said. “I always ask my students at the end, ‘Did you learn more from me, or did I learn more from you?’

“I usually win.”

CPR/AED certification and awareness may save lives

February 20, 2017

Heart Health Awareness Month underscores automated external defibrillator training at Arizona State University.

Anyone may use an AED to analyze a heart rhythm and, if necessary, deliver an electrical shock to re-establish a rhythm in an abnormal or stopped heart. The AED machine talks to the user and gives step by step instructions. 

 

Public-access AEDs are located in common areas of many university buildings such as first-floor corridors, near the main restrooms or by elevators.

AEDs are also located in:

  • Athletic venues
  • ASU Police vehicles
  • Fulton Center
  • New or renovated buildings since 2007
  • Residential halls
  • Student unions 

View more than 300 ASU AED locations.

“In an emergency, call 911 and use the CPR/AED skills we teach in our awareness classes,” said Alex Gutierrez, ASU’s AED program manager. “AED training may help you save someone’s life.”

To use an AED, you don’t need to be certified. Environmental Health and Safety offers in-person CPR/AED awareness training. If you want to be certified, Sun Devil Fitness hosts CPR/AED certification and ASU partner Emergency University offers online CPR/AED certification.

AED devices save lives

Geography senior Josh Groth works at the Tempe Sun Devil Fitness Center as an aquatic student coordinator. He also taught an AED/CPR and First Aid certification classes. He said certification gives confidence in emergency situations and that the training is easy to complete. 

“The certification class is only about four hours long, and it’s a great mix of hands-on practice and information,” Groth said. “The instructors are invested in getting participants certified, so there is plenty of help during classes.”

For anyone at ASU who would like to take an awareness training, a certified CPR/AED instructor leads EHS’s free, 90-minute awareness training, but it will not result in certification. Participants learn chest compression CPR and how to use an AED.

ASU is recognized by the Arizona Department of Health Services as a Heart Safe organization. Visit the EHS AED webpage for more information.
