Trions exhibit novel characteristics in moiré superlattices

When two similar atomic layers with mismatching lattice constants—the constant distance between a layer's unit cells—and/or orientation are stacked together, the resulting bilayer can exhibit a moiré pattern and form a moiré ...

Physicists observe modified energy landscapes at the intersection of 2D materials

In 1884, Edwin Abbott wrote the novel Flatland: A Romance in Many Dimensions as a satire of Victorian hierarchy. He imagined a world that existed only in two dimensions, where the beings are 2D geometric figures. The physics ...

2D materials combine, becoming polarized and giving rise to photovoltaic effect

For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged. ...

Moiré patterns facilitate discovery of novel insulating phases

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 ...
