Abstract

A hydrodynamic model of plasmonic crystals in current-driven grating-gate transistor structures shows that DC bias can make plasma modes optically active and split resonant absorption peaks, revealing tunable band gaps in the plasmonic band spectrum. The analysis predicts current-tunable absorption features, enhanced coupling to THz radiation, and potential microwave-to-THz frequency conversion in grating-gated TeraFET structures across multiple 2D material platforms.
