Atomic Pulses Tune 2D Semiconductor Alloys for Future Quantum Materials (opens in new tab)

Researchers used pulsed sub-atomic layer deposition to control both composition and metal-atom distribution in Mo-W-S2 monolayers across the full MoS2-to-WS2 range. The study shows how engineered line structures and elongated islands can shift excitonic emission, pointing toward future quantum-dot and quantum-wire-like 2D materials.
