Abstract

In small semiconductor devices, electrons show a wave property. Electrons coming to a quantum well are partly reflected and partly transmitted at the well. The electron motion in semiconductor diodes including the quantum well is studied. Under conditions where the energy of the electrons coming to the quantum well can be controlled by an external field, current-voltage characteristics of the diodes are calculated. Preliminary results show anomalous current-voltage characteristics and the possibility of a negative resistance due to transmission resonance.
