Query: Toward durable Al-InSb hybrid heterostructures via epitaxy of 2ML
  interfacial InAs screening layers   The large Land\'{e} g-factor, high spin-orbit coupling, and low effective
mass of the two-dimensional electron gas in InSb quantum wells combined with
proximal superconductivity may realize a scalable platform for topological
quantum computation. Aluminum thin films directly deposited on top of InSb
planar structures result in the formation of a reactive AlInSb layer at the
interface. This interlayer progressively consumes the whole Al film, resulting
in a disordered AlInSb layer after few months at room temperature. We report on
a heterostructure design that results in a significant increase of the
durability of these hybrid Al-InSb heterostructures with the preservation of a
pure Al film and sharp superconductor-semiconductor interface for more than one
year. Two monolayers of epitaxial InAs at the superconductor-semiconductor
interface prevent interfacial reactivity as evidenced by X-ray reflectivity and
energy dispersive spectroscopy measurements. Structural characterizations of
the Al films by transmission electron microscopy reveal the presence of tens of
nanometers wide grains predominantly oriented with Al(110) parallel to
InSb(001).
