Abstract
We report the experimental study of the thermionic emission of electro ns into overbarrier states of a superlattice, tailored to enhance elec tron confinement within a closely spaced quantum well. Partial suppres sion of the thermionic current is observed at room temperature. A crit ical evaluation of the practical applications of the effect is offered . Furthermore, the tunnel injection into partially delocalized Stark s tates of the superlattice is observed at low temperature. (C) 1994 Ame rican Institute of Physics.
