Transition metal dichalcogenides (TMDs) have rapidly emerged as one of the most attractive families of two-dimensional materials due to their numerous outstanding electronic and optoelectronic properties. TMDs have layer-dependent band structures, exhibiting a dramatic transition from a direct bandg...
