Abstract Intra-atomic orbital hybridization and interatomic bond formation are the two fundamental processes when real atoms are condensed to form matter1,2. Artificial atoms mimic real atoms by demonstrating discrete energy levels attributable to quantum confinement3,4,5,6,7,8. As such, they offer a solid-state analogue for simulating intra-atomic orbital hybridization and interatomic bond formation.

Control of doping and carrier concentration at the nanoscale is an essential requirement to realize future electronic and optoelectronic devices in two-dimensional van der Waals (vdW) heterostructures. In spite of great efforts on the related study, introducing nanoscale high-quality junctions with custom-designed sizes and sites remains an outstanding challenge in experiments.
