Abstract
We calculate the spectrum and damping rate of plasma oscillations in a two-dimensional electron channel with striplike side contacts, taking into account the finite value of the conductivity of side contacts. We use a hydrodynamic electron-transport model for electrons both in the two-dimensional electron channel and contacts, with the Poisson equation for the self-consistent electric potential. It is shown that in the real channels the damping rate can markedly increase due to the influence of nonideally conducting side contacts.
