Implication

Experimental findings demonstrate that graphene modifies optical properties in terahertz plasmonic crystals, suggesting improvements in electron control.

Key Points

  • The research aims to investigate how graphene affects the optical properties of AlGaN/GaN plasmonic crystals.
  • Experimental study of AlGaN/GaN grating-gate terahertz plasmonic crystals with and without graphene
  • Analysis of localized and delocalized plasmon modes under varying gate voltages
  • CVD graphene eliminates localized plasmon modes at sub-threshold gate voltages
  • Graphene weakly affects delocalized modes above the threshold
  • High resistance of CVD graphene influences electron concentration at the interface
