Hyperbolic polaritons in twisted β-Ga2O3

npj Nanophotonics
Hyperbolic polaritons (HPs) are essential for integrated photonics due to their directional propagation and strong field confinement. While most research focuses on in-plane light behavior, the out-of-plane features of HPs remain underexplored.

Impact of the angular alignment on the crystal field and intrinsic doping of bilayer graphene/BN heterostructures

The energy gap of Bernal-stacked bilayer graphene can be tuned by applying a perpendicular electric field. The origin of this gap can be traced down to the breaking of its inversion symmetry by an onsite potential difference between the layers.
