Spicing Up 2D Transition Metal Dichalcogenides with Substitutional Dopants

2D semiconductors provide an exciting platform to engineer atomic quantum systems in a robust, yet tunable solid-state system. In this colloquium, I will present our efforts to unravel the interesting physics behind single dopant atoms in transition metal dichalcogenide (TMD) monolayers by means of high-resolution scanning probe microscopy. By targeted chemical doping of semiconducting TMDs, we identify the interplay between chemical impurity states, multi-valley hydrogenic bound states, spin-orbit coupling, and electron-phonon interaction at reduced dimensions.
