foundation for future two-dimensional (2D) device technology. However, the traditional
approach to creating a heterojunction by direct growth of a heterostructure of two different
materials constrains the available band offsets, and it is still unclear if large built-in potentials
are attainable for 2D materials. The electronic properties of atomically thin semiconducting
transition metal dichalcogenides (TMDs) are not static, and their exciton binding energy and …
