| Abstract: | Bollzmann's equation is solved for an clectmn m lhe lowest miniband of a superlattice semiconductor under the influence of an fxlemal electric field E(t). The currentdensity electric field characteristic shows a negalive differential mnductivity when WT a 1 (quasialalic case). This arum in lhe neighbourhood where lhe conslant electric field EO h qual to lhe amplitude of Ihe AC elec'ric field E1 and the peak decreases wilh increasing Et |
