One-Dimensional Nature of Pairing and Superconductivity at the LaAlO${}_3$/SrTiO${}_3$ Interface

Yun-Yi Pai, Hyungwoo Lee, Jung-Woo Lee +8

We examine superconductivity in LaAlO${}_3$/SrTiO${}_3$ channels in which the channel width transitions from the 1D to 2D regime. The superconducting critical current is independent of…
