  abstract = {The ability to control the size of the electronic bandgap is an integral 
 part of solid-state technology. Atomically thin two-dimensional crystals 
 offer a new approach for tuning the energies of the electronic states 
 based on the unusual strength of the Coulomb interaction in these 
 materials and its environmental sensitivity. Here, we show that by 
 engineering the surrounding dielectric environment, one can tune the 
 electronic bandgap and the exciton binding energy in monolayers of WS2 
 and WSe2 by hundreds of meV. We exploit this behaviour to present an 
 in-plane dielectric heterostructure with a spatially dependent bandgap, 
 as an initial step towards the creation of diverse lateral junctions 
 with nanoscale resolution.},
