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 of such a world is
somewhat akin to that of modern 2D materials, such as graphene and
transition metal dichalcogenides, which include tungsten disulfide
(WS2), tungsten diselenide (WSe2), molybdenum disulfide (MoS2) and
molybdenum diselenide (MoSe2).
Physicists observe modified energy landscapes at the
intersection of 2D materials
