> It's a 2D crystal of electrons that live in a thin semiconductor that is sandwiched between two layers of other semiconductor. You can't pick it with a tiny gripper. Somehow as a layman I suspect it isn't a crystal in the lay "stays super stable for super long periods with no energy input" sense, but in some other scientific sense. Can a future, more advanced version of this structure theoretically store energy in this form?
