We refine the determination of the equilibrium density distribution in a grid-gated double-quantum-well FET, taking account of screening in the system using the Poisson equation. This calculation provides requisite input information needed for the analysis of plasmon-mediated photoconductivity resonances observed in the recent experiments of Peralta and Allen. We show that the heights of the terahertz photoconductance peaks correlate with resonant terahertz plasmon absorbance.
