Magneto-transport study of top- and back-gated LaAlO3/SrTiO3 heterostructures

Magneto-transport study of top- and back-gated LaAlO3/SrTiO3 heterostructures

We report a detailed analysis of magneto-transport properties of top- and back-gated LaAlO3/SrTiO3 heterostructures. Efficient modulation in magneto-resistance, carrier density, and mobility of the two-dimensional electron liquid present at the interface is achieved by sweeping top and back gate vol...
