L64.00004. Transport properties of non-reciprocal 1D quantum channels at LAO/STO interface

Presented by: Yuze Zhang


Abstract

Complex oxide heterostructures exhibit many interesting phenomena [1] that can be controlled on the nanoscale using a conductive atomic force microscope (c-AFM) lithography technique [2]. We create chiral 1D superlattices at the LaAlO3/SrTiO3 interface by adding a periodic modulation to an electron waveguide device. These nanostructures support quantized ballistic transport of electrons and electron pairs, as well as oscillatory transport behavior indicating an engineered spin orbit interaction [3]. These experiments represent a first step toward engineering properties in 1D quantum wires and can be regarded as a building block for more complex quantum systems. [1] Y-Y.
