Microscopy images could lead to new ways to control excitons for quantum computing

"localize excitons on specific lattice sites by stacking these 2D materials... stacking layers of tungsten disulfide (WS2) and tungsten diselenide (WSe2)... small mismatch in spacing of atoms causes moiré superlattice... large atomic reconstructions take place in stacked materials, which modulate electronic structure to form periodic array of traps where excitons become localized... direct relationship between structural changes and localization of excitons enables new approach to optoelectronic materials"
