researcher (IMAGE) Rice University Caption Rice University postdoctoral research associate Jianwei Huang with the laboratory apparatus he used to conduct angle-resolved photoemission spectroscopy experiments on a copper-vanadium alloy. The experiments showed the alloy is the first known material in which 3D crystal structure and strong quantum interactions frustrate the movement of electrons and lock them in place, resulting in a flat electronic band.
