Expérimental et théorique Description
Recent improvements in cryogenic and nanofabrication allow us not only show concepts of superconducting electronics but open a path to a real competition against semiconducting one. One of a basic element of any circuits is the diode. One of possible realizations of the superconducting diode is based on the operation of Abrikosov vortices. The main advantages of this type is a relative fabrication simplicity. But optimization are still required in terms of design and operating protocols. Coupling vortices with external periodic drive can lead to effect of their synchronous motion . Using that effect, it is possible to make a digital version of the superconducting diode: vortices move synchronously “1” or asynchronously “0”. In this internship we propose to study properties of a vortex-based superconducting diode and optimizing its parameters for the best efficiency.
