Surface Acoustic Wave Generation and Detection on LAO/STO

ORAL

Abstract

We aim to observe Surface Acoustic Wave (SAW) in LAO/STO heterostructures. Using well-developed conductive-AFM lithography, one can switch between the conducting and insulating phases of the material, thus interdigited transducers (IDT) can be created in the structure, which can convert electronic signals into acoustic signals and vice versa. Two IDTs are thus written on the structure as a generator and a detector. Due to material and dimensional constraint, a radio frequency electronic signal is used to maximize the effect. SAW can generate potential minima relying on the piezoelectric property of LAO/STO, and by changing position of these potential minima electrons can be transported along the nanowire, which is an emerging option for quantum information transfer.
