Abstract
An electron wave interference device includes a source electrode for injecting electrons therethrough, a drain electrode for taking out electrons therethrough, channel means for propagating electrons from the source electrode to the drain electrode and a gate electrode provided on a halfway portion of the channel means between the source electrode and the drain electrode for dividing the channel means into plural channels solely in the halfway portion of the channel means. A positional relationship between the channel means and the gate electrode is set so that a depletion layer is extended under the gate electrode toward the channel means by applying a given voltage to the gate electrode. The depletion layer extended through the channel means forms an island which inhibits the propagation of electrons in the channel means and thus divides the channel means into the plural channels.
