Researchers at Rice University have discovered an alloy of copper, vanadium, and sulfur that forms crystals capable of trapping electrons due to quantum effects, resulting in flat bands with unique properties. This marks the first instance of a 3D crystal exhibiting this behavior, potentially holding significance for future quantum computers and the development of room-temperature superconductors.
Rice University scientists have discovered a 3D crystalline metal, a copper-vanadium-sulfur alloy, in which quantum correlations and crystal structure frustrate electron movement, resulting in a flat electronic band. The study, published in Nature Physics, details the theoretical design principle and experimental methodology used to find the material, which features a 3D pyrochlore lattice. The discovery may lead to new states of matter and potential applications, and the research team's predictive methodology could aid in identifying other materials with similar properties.
