Query: Nonlinear feedback oscillations in resonant tunneling through double
  barriers   We analyze the dynamical evolution of the resonant tunneling of an ensemble
of electrons through a double barrier in the presence of the self-consistent
potential created by the charge accumulation in the well.
  The intrinsic nonlinearity of the transmission process is shown to lead to
oscillations of the stored charge and of the transmitted and reflected fluxes.
  The dependence on the electrostatic feedback induced by the self-consistent
potential and on the energy width of the incident distribution is discussed.
