Semimetals are High Conductors (IMAGE) University of California - Davis Caption Weyl semimetals are a new type of material between conductors and insulators. New work from UC Davis and Chinese researchers shows that two-dimensional nanobelts of niobium arsenide can show very high conductivity. On left, transmission EM of niobium arsenide nanobelts fabricated on the lab; the right-hand image is a higher magnification scanning EM showing the regular surface structure. Electrical current can flow easily because of the quantum properties of the nanomaterial. Credit Sergey Savrasov, UC Davis Usage Restrictions May be used with acknowledgement.
