Both can be understood in principle by magnon excitations and interactions with magnons, as well as due to tunnelling with respect to localized states induced by oxygen vacancies ( see Symmetry Filtering section hereafter ).

Once there, the electron can move through the crystal, for a brief amount of time, before relaxing into another localized state ( in other words, " sticking " to a different atom ).

All these remarks apply in principle to Fowler Nordheim tunneling from any conductor where ( before tunneling ) the electrons may be treated as in localized states at or very close inside the emitting surface, but this is beyond the scope of this article.

It is available to authorized local, state, and law enforcement and criminal justice agencies via any of the three law enforcement communication systems National Law Enforcement Telecommunications System ( NLETS ), a more localized state criminal information system ( name varies by state ), and the International Law Enforcement Telecommunications System ( INLETS ).
