The steady state drain current of a pseudomorphic high-mobility field effect transistor has been calculated by the Monte Carlo particle method. We observe temporal fluctuations in it which are caused by formation of unstable vortices in the current path near the drain contact. These fluctuations manifest themselves as noise in the high gigaherz and low teraherz frequencies and may represent the main source of noise in this frequency range. © 2000 American Institute of Physics.
