P. Kleinert, BALANCE-EQUATIONS FOR HOT-ELECTRON TRANSPORT WITH INTRA-COLLISIONAL FIELD EFFECTS, Physica. B, Condensed matter, 245(3), 1998, pp. 225-232
The balance equation approach is generalized to account for intra-coll
isional field effects. Specific results are derived for the miniband t
ransport in a semiconductor superlattice. The inclusion of intra-colli
sional field effects into the balance equations gives rise to sizable
quantitative changes of the drift velocity but does not lead to more q
ualitative modifications of the current-voltage characteristics which
are due to Wannier-Stark localization. (C) 1998 Elsevier Science B.V.
