Superconducting Diode Effect via Conformal-Mapped Nanoholes

In a study published in Nature Communications, researchers prepared a superconducting diode with thin film patterned with nanoscale holes.

Scientific Achievement

A superconducting diode is dissipation-less and desirable for electronic circuits with ultralow power consumption. Such a device was achieved in a conventional super-conducting film patterned with a conformal array of nanoscale holes.

Significance and Impact

The switchable and reversible rectification signals can be three orders of magnitude larger than those from a flux-quantum diode.

Research Details

  • The superconducting diode effect is achieved in conventional MoGe superconducting films (50 nm thick) patterned with a conformal array of nanoscale holes (110 and 220 nm diameter) to break the spatial inversion symmetry.
  • The primary CNM capabilities used included optical and electron beam lithography and reactive ion etching.

Work was performed in part at CNM.
