LWLiyan WangKFKaijun FengSLShuai Liu

Key Points

  • This research aims to develop a platform for twist-polaritonics using non-van der Waals materials, specifically β-Ga₂O₃ nanoflakes.
  • Developed β-Ga₂O₃ nanoflakes with atomically smooth surfaces.
  • Investigated stacking configurations and their impact on light-matter states.
  • Utilized advanced optical techniques to analyze polariton behavior.
  • Demonstrated successful creation of light-matter states in β-Ga₂O₃ nanoflakes.
  • Achieved unprecedented control over the properties of polaritons with twist configurations.
  • Highlighted the potential of non-van der Waals materials in nanoscale optics.

Abstract

Twist‑polaritonics provides precise control of light-matter states through the stacking of atomically smooth, anisotropic layers but has been restricted to van der Waals (vdW) crystals. Non‑vdW crystals, despite their symmetry‑broken...
