Magnetic Field Can 'Toggle' Carbon Nanotube

Facebook X LinkedIn Email
CHAMPAIGN, Ill., May 20 -- By threading a magnetic field through a carbon nanotube, scientists have switched the molecule between metallic and semiconducting states, a phenomenon predicted by physicists some years ago, but never before clearly seen in individual molecules. Researchers from the University of Illinois at Urbana-Champaign have shown that a nanotube's electronic structure can be altered in response to a magnetic field. The research team consisted of physics professors Alexey Bezryadin and Paul Goldbart, postdoctoral research associate Smitha Vishveshwara and graduate students...Read full article
