Phosphorus chains reveal pure one-dimensional electrons

Electrons confined within self-assembled phosphorus chains have been shown to move in a strictly one-dimensional manner, marking a significant advance in condensed matter physics and nanomaterials research. The breakthrough offers a rare experimental confirmation of behaviour long predicted by theory and points to a pathway for engineering materials whose electronic states can be tuned simply by adjusting atomic spacing. The international research team demonstrated that phosphorus atoms, when arranged in ultra-thin chains on a suitable surface, support electrons that behave as if they are restricted to a single spatial dimension. By deploying high-resolution scanning probe microscopy...
