Nanotubes and Silicon: Unexpected Ingredients in a New Optical Device
He and Yung Joon Jung, an associate professor of mechanical and industrial engineering, have received a three-year, $309,000 National Science Foundation grant to explore a phenomenon they discovered entirely by chance, which could afford a new generation of extremely efficient electronics.
Kar’s expertise is in the physics of graphene, which is a sheet of carbon atoms, one-atom-thick. Because of its structure, graphene is a superior thermal and electric conductor. Jung’s work focuses on the mechanics of carbon nanotubes, or nanometer-sized rolled-up sheets of graphene.
“The two materials are closely related in many ways,” said Kar.
Last year, the Provost’s office awarded Jung and Kar a Tier 1 Interdisciplinary Seed Grant to develop new optoelectronic and solar devices using both graphene and carbon nanotubes.
