Abstract

A study of electron-wave interference effects in a structure which is comprised of a split-gate point contact with a parallel reflector gate is reported. The structure constricts the injected electrons to a waveguide. The variation of point contact conductance with reflector voltage has novel oscillations directly related to the one-dimensional (1D) states in the waveguide. The oscillations are caused by the change in matching between a mode for the 1D waveguide state and an electron wave injected into the states. The oscillations are also found to be quenched with weak magnetic fields due to electron wave deflection.
