Stacking various atomically-thin crystals on top of one another can strongly modify their overall properties. When two materials are stacked with a twist angle, a geometric interference pattern (a moiré pattern) emerges. At special twist angles, the moiré pattern can result in new electronic states dominated by strong correlations between electrons.
We have developed a solution-phase protocol to modify the Lewis basic surface of few-layer black phosphorus (bP) using commercially available Lewis acids, and demonstrated its effectiveness at providing outstanding ambient stability and tuning of electronic properties.
In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed in metals rather than insulators, and its discovery offers new insights into our understanding of the quantum world. The findings also hint at the existence of an entirely new type of quantum particle.
Welcome to the internet hub of the Materials Research Science and Engineering Centers (MRSEC), a network of Centers located at academic institutions throughout the United States, funded by the National Science Foundation. This website provides organized connections to information and resources at the various MRSECs for the international scientific, industrial, and educational materials research and development communities.
