Manipulation of phase shift in antidot three-dimensional topological insulator Josephson junctions

POSTER

Abstract

Topological insulator/superconductor (TI/SC) heterostructures are a promising platform to realize topological superconductivity and hence manipulate Majorana zero modes (MZMs). In TI/SC hybrids, an antidot in the SC can pin vortices and accommodate MZMs. We employed antidots in TI/SC Josephson junction devices and observed controllable manipulation of phase shift in the Josephson effect.
