title: One-dimensional quantum wire formed at the boundary between two insulating LaAlO3/SrTiO3 interfaces.
abstract: We grow a tiled structure of insulating two-dimensional LaAlO3/SrTiO3 interfaces composed of alternating one and three LaAlO3 unit cells. The boundary between two tiles is conducting. At low temperatures this conductance exhibits quantized steps as a function of gate voltage indicative of a one-dimensional channel. The step size of half the quantum of conductance is evidence for the absence of spin degeneracy.
