Zs. Gribnikov et al., BALLISTIC DIODES WITH DOUBLE-QUANTUM-WELL SEGMENTS IN THEIR BASES, Physica status solidi. b, Basic research, 204(1), 1997, pp. 497-499
It is shown that a current-voltage characteristic of a ballistic diode
with space charge limited longitudinal electron transport through a q
uantum structure consisting of a double quantum well segment is of a m
ultiextremum character with repeated N-shaped (or Z-shaped) parts.
