arXiv:cond-mat/0606264 · doi:10.1016/j.sse.2007.09.002
Abstract
We analyze the current instability of the steady state with a direct current for an ungated two-dimensional(2D) electron layer for arbitrary current and the carrier scattering strength. We demonstrate the possibility of single-mode generator operating in terahertz frequency range.
