Query: Towards half-metallic interfaces: the Co$_2$CrAl/InP contacts   Although the interest on half-metallic Heusler alloys, susceptible to be used
in spintronic applications, has considerably grown, their interfaces with
semiconductors show very low spin-polarization. I identify mechanisms which can
keep the high spin-polarization at the interface (more than 80% of the
electrons at the Fermi level are of majority spin) although the
half-metallicity is lost. The large enhancement of the Cr moment at the
interface between a CrAl terminated Co$_2$CrAl(001) spacer and the InP(001)
semiconductor weakens the effect of the interface states resulting in this high
spin-polarization. On the other hand the Co$_2$CrAl/InP interfaces made up by a
Co layer and either an In or a P one show a severe decrease of the Co spin
moment but Cr in the subinterface layer is bulklike and the resulting
spin-polarization is similar to the CrAl-based interfaces.
