RIVERSIDE, Calif. Materials having excess electrons are typically conductors. However, moiré patterns interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern can suppress electrical conductivity, a study led by physicists at the University of California, Riverside, has found.
In the lab, the researchers overlaid a single monolayer of tungsten disulfide (WS
2) on a single monolayer of tungsten diselenide (WSe
2) and aligned the two layers against each other to generate large-scale moiré patterns. The atoms in both the WS
2 and WSe
