Extended Data Fig. 3: Magnetotransport data for vertical superlattice Device B2.
From: One-dimensional Kronig–Penney superlattices at the LaAlO3/SrTiO3 interface
a, Transconductance map dG/dVsg as a function of side gate voltage Vsg and magnetic field B. Purple regions indicate conductance plateaus, that is, zero transconductance. Red/yellow/green/blue regions indicate increases in conductance when new subbands become available. Colored boxes are guides to the eye indication the location of highlighted conductance curves. b, Plot showing full conductance data. Each curve is colored according to the transconductance at each side gate value (white indicates a plateau, black indicates rapidly increasing conductance). Curves are offset clarity. c, d, Conductance G as a function of side gate voltage Vsg curves at different out-of-plane magnetic field B values highlighting some fractional conductance features. T=50 mK.
