Topological insulator based axial superconducting quantum interferometer structures

Superconductor Science and Technology, vol. 37, pp. 085028

Abstract

Abstract Nanoscale superconducting quantum interference devices are fabricated in-situ from a single Bi0.26Sb1.74Te3 nanoribbon that is defined using selective-area growth and contacted with superconducting Nb electrodes via a shadow mask technique. We present h / ( 2 e ) magnetic flux periodic interference in both, fully and non-fully proximitized nanoribbons. The pronounced oscillations are attributed to interference effects of coherent transport through the topological surface states encompassing the cross-section of the nanoribbon.
