Extended Data Fig. 2: Device B1 1.8 Feature.
From: One-dimensional Kronig–Penney superlattices at the LaAlO3/SrTiO3 interface
a, Conductance data - same as shown in Extended Data Fig. 1b. b, Zoom on region highlighting feature at G ≈ 1.8e2/h. Red lines are guides to the eye to show that the feature near 1.6 is in fact 0.2 below the 2e2/h plateau, which itself is not fully resolved until the highest magnetic fields.
