UCLA advance with new nanomaterials good news for next-generation electronic devices
Description
In a study published today in Nature Nanotechnology, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science and from the materials division of Australia’s University of Queensland show the promise of surface-conduction channels in topological insulator nanoribbons made of bismuth telluride and demonstrate that surface states in these nanoribbons are “tunable” — able to be turned on and off depending on the position of the Fermi level.
“Our finding enables a variety of opportunities in building potential new-generation, low-dissipation nanoelectronic and spintronic devices, from magnetic sensing to storage,” said Kang L. Wang, the Raytheon Professor of Electrical Engineering at UCLA Engineering, whose team carried out the research.
