Semimetals are High Conductors

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.
