Two-Dimensional Crystal

Caption

A two-dimensional crystal from molybdenum disulfide (MoS2) and Tungsten diselenide (WSe2) (left: top view, right: side view). Light can produce interlayer excitons in these crystals, which are fascinating excited states, consisting of one particle of positive charge and one of negative charge. The coloured outlines in the right picture represent the probability of the particles' places.
