Electronic Transport in InSb Nanowires with Ferromagnetic Contacts

ORAL

Abstract

InSb nanowires have been established as a versatile materials platform for realizing Majorana bound states and for investigating spin-orbital interaction (SOI) and large effective g-factor. By coupling InSb nanowires to ferromagnetic (FM) contacts, a spin-polarized current can be injected into the nanowires and subsequently controlled by electric fields. Moreover, when only a single subband is occupied, such nanowires are expected to host a spin-helical liquid, which acts as an efficient quantum spin-filter. We will report on our progress fabricating nanowire devices with FM electrodes in spin-valve geometry, as well as discussing our low-temperature transport experiments on these devices.
