Query: Giant Plasmon Instability in Dual-Grating-Gate Graphene Field-Effect
  Transistor   We study instability of plasmons in a dual-grating-gate graphene field-effect
transistor induced by dc current injection using self-consistent simulations
with the Boltzmann equation. With only the acoustic-phonon-limited electron
scattering, it is demonstrated that a total growth rate of the plasmon
instability, with the terahertz/mid-infrared range of the frequency, can exceed
$4\times10^{12}$ s$^{-1}$ at room temperature, which is an order of magnitude
larger than in two-dimensional electron gases based on usual semiconductors. By
Comparing the simulation results with existing theory, it is revealed that the
giant total growth rate originates from simulataneous occurence of the
so-called Dyakonov-Shur and Ryzhii-Satou-Shur instabilities.
