Electrostatically tuned dimensional crossover in LaAlO3/SrTiO3 heterostructures

We report a gate-tunable dimensional crossover in sub-micrometer-scale channels created at the LaAlO3/SrTiO3 interface. Conducting channels of widths 10 nm and 200 nm are created using conducting atomic force microscope lithography. Under sufficient negative back-gate tuning, the orbital magnetocond...
