title = "Non-linear Doppler shift of the plasmon resonance in a grating-coupled drifting 2DEG",
abstract = "Plasmon resonances of a two-dimensional electron gas (2DEG) in the far infrared region have been evaluated. This study was done to observe the effects of laterally drifting the 2DEG, that is giving the electrons a net velocity in the plane of the charge sheet. A simple description of the effects of drifting is in terms of a Doppler shift in the plasmon frequency. These effects are studied both through experiments and computations. Using the scattering matrix method to model electromagnetic response of stratified systems including gratings and 2DEG's, it includes a full electromagnetic field calculation which takes into account the screening effects of the grating. Calculation of the plasmon frequency as a function of drift velocity will show that there is a splitting at zero drift velocity caused by periodic grating gate screening and that the plasmon frequency shift is not linear with the drift velocity. However, the calculated plasmon frequencies of the 2DEG with a grating coupler do approach the linear Doppler shift at sufficiently high drift velocities.",
