Confinement in a Double Barrier Structure in the Presence of an Electric Field
The effect of electric field on the electron resonant tunnelling into a
double barrier structure is studied. We show for particular field strengths an
increase of the tunnelling time which leads us to explain the Stark-ladder
localization and Bloch oscillations in superlattices and to discuss the
quenching of luminescence in multiple quantum wells.Comment: Latex 7 pages with 4 figures. The figures are included in this
version and the figure caption is slightly modifie
