Quantum interference semiconductor device
 A quantum interference semiconductor device using the interference effect of electron waves has a cathode, an anode, and a gate which are mounted in a vacuum. An electron wave which is emitted from the cathode into the vacuum is divided into a plurality of electron waves and, subsequently, the plurality of electron waves are combined at the anode. Phase differences among the plurality of electron waves are controlled by the gate, thereby making the device operative.
