Article Summaries:
- Scientists have identified a microscopic mechanism that allows precise tuning of the magneto‑optical properties of excitons in alloys of two‑dimensional semiconductors. By controlling how excitons-bound electron‑hole pairs-respond to magnetic fields, researchers can manipulate the valley degree of freedom, a key element in valleytronics. The discovery, detailed in Physical Review Letters, suggests that alloy engineering could enable practical devices that exploit valley‑dependent electronic states, potentially advancing next‑generation optoelectronic technologies.
