Amit Goyal

The National Academy of Inventors has elected Amit Goyal as a fellow. Goyal is a researcher at the U.S. Department of Energy’s Oak Ridge National Laboratory.

The organization recognized Goyal for “having demonstrated a highly prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development, and the welfare of society.”

The National Academy of Inventors was founded in 2010 with goals that include celebrating and encouraging inventors, enhancing awareness of technology and innovation, and communicating the work of its members to benefit society.

Goyal, a member of ORNL’s Materials Science and Technology Division, is an international leader in the field of energy and electronic materials, particularly high-temperature superconducting materials. He has more than 80 issued patents. [Read more…]

SEATTLE—University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics, thanks in part to a breakthrough by researchers at Oak Ridge National Laboratory and University of Tennessee in Knoxville.

The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

Most consumer electronics use three-dimensional LEDs, but they are up to 20 times thicker than the LEDs being developed. [Read more…]
