Seong Jin Koh, an associate professor in the Materials Science & Engineering Department, has received a $300,000 National Science Foundation grant that could lead to a tenfold reduction in energy consumption of smart phones, laptops and tablets, which could result in an identical reduction in the frequency of battery charging for those devices.

"The key is that all transistor components reside in a single nanopillar and that electrons flow through it without being heated," said Koh, who added that a nanopillar is less than 50 nanometers in diameter. A human hair is about 100,000 nanometers thick. "This research will allow transistors to consume less energy and generate less heat. That greatly affects how well the transistors perform."

Khosrow Behbehani, dean of the College of Engineering, said other sectors besides individual electronic component users stand to benefit too.
