Scientists confirm one-dimensional electron behavior in phosphorus chains

For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they separated the signals from chains aligned in different directions to reveal their true nature. The findings suggest that squeezing the chains closer together could trigger a dramatic shift from semiconductor to metal. That means simply adjusting density could unlock entirely new electronic states.
