Abstract: Nanoscale superconducting quantum interference devices are fabricated in-situ from a single Bi_0.26Sb_1.74Te_3 nanoribbon that is defined using selective-area growth and contacted with superconducting Nb electrodes via a shadow mask technique. We present h/2e 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.
