Nonuniform motion of high-field domains in the Gunn effect

In recent publications, rules have been established for obtaining the properties of the high-field domain traversing in a steady state across Gunn diodes. This letter shows that these steady-state properties cannot be reconciled with the formation stage of the domain without some extension of the theory to include the non-steady-state domain. This letter provides the necessary extension of these rules and concludes with a qualitative account of the domain dynamics from the formation stage up to equilibrium.
