Giant g-factors and fully spin-polarized states in metamorphic short-period InAsSb/InSb superlattices
Abstract
<jats:title>Abstract</jats:title><jats:p>Realizing a large Landé <jats:italic>g</jats:italic>-factor of electrons in solid-state materials has long been thought of as a rewarding task as it can trigger abundant immediate applications in spintronics and quantum computing. Here, by using metamorphic InAsSb/InSb superlattices (SLs), we demonstrate an unprecedented high value of <jats:italic>g</jats:italic> ≈ 104, twice larger than that in bulk InSb, and fully spin-polarized states at low magnetic fields. In addition, we show that the <jats:italic>g</jats:italic>-factor can be tuned on demand from 20 to 110 via varying the SL period. The key ingredients of such a wide tunability are the wavefunction mixing and overlap between the electron and hole states, which have drawn little attention in prior studies. Our work not only establishes metamorphic InAsSb/InSb as a promising and competitive material platform for future quantum devices but also provides a new route toward <jats:italic>g</jats:italic>-factor engineering in semiconductor structures.</jats:p>
