摘要

In the Dyakonov-Shur detector the plasma resonance in a short channel High Electron Mobility Transistor is used for the resonant tunable detection of terahertz radiation. We derived a viscous hydrodynamic model with temperature dependent transport coefficients for the gated conduction channel. We evaluated the detector response function and obtained the quality factor of the plasma resonance.
