Abstract
We have built and investigated an electronic interferometer based on a 2D electron gas in a AlGaAs/GaAs heterojunction. This is the smallest interferometer that has ever been built. We established that at T < 0 . 1 K the amplitude of the Aharonov-Bohm oscillations of the interfero meter reaches 35% of the resistance of the interferometer in the absen ce of a magnetic field; this is almost twice the amplitude previously achieved.
