Atom-Precision Synthesis of MoS2/WS2 Lateral Heterostructures for Prolonged Excitonic Lifetime.
Transition metal dichalcogenide (TMD) lateral heterostructures provide unique platforms to study nanoscale physics, but progress is limited by the difficulty of producing high-quality interfaces, which require atomic-precision growth rather than simple stacking. We report a controllable two-step chemical vapor depositi...
