Abstract :
We describe three-terminal operation of a quantum interference device using a quantum wire with a stub structure. Clear periodic conductance oscillations as a function of stub-tuner gate voltage, by which a stub length is independently controlled, were observed. The observed periodic conductance oscillations can be explained quite well by taking conductance modulation through the quantum interference of electron waves in the stub into consideration.<>
