• Scientists confirm one-dimensional electron behavior in phosphorus chains Atom-thin phosphorus chains have been shown to host true 1D electronsâ and squeezing them tighter could turn them metallic. • Researchers at BESSY II have, for the first time, experimentally confirmed that a material can exhibit truly one-dimensional electronic properties. • The team studied short chains of phosphorus atoms that naturally arrange themselves at specific angles on a silver surface. • By applying advanced measurement and analysis techniques, they separated the signals coming from chains aligned in different directions. • This careful work showed that each individual chain behaves as a genuine one-dimensional electronic system. • The findings also point to a dramatic shift in behavior depending on how closely the chains are spaced.
