    • This large variation in the diameter is typical for the thin film Au technique, where the diameter of the catalyst particles determining the size of the NWs shows a large statistical spreading. The variance in diameter, however, depends on the oxide desorption parameters as well as on the thickness of the Au film and can be tuned by adjusting these parameters.

    • The six side facets of the NWs are a subset of the crystal plane class {211}, with the [111] direction being parallel to the planes, namely, (2̄11), (1̄1̄2), (12̄1), (21̄1̄), (112̄), and (1̄21̄).

    • The Mn flux was determined by RHEED oscillations of 2D growth of MnAs films on (001) GaAs for various temperatures of the Mn cell. With the obained correlation, the Mn flux and hence the Mn concentration for the specific Mn cell temperature used during NW growth could be estimated.

    • An orientation-dependent efficiency of Mn incorporation and/or an orientation-dependent As antisite defect density are discussed as possible reasons for the reduced TC values. For the (110) orientation a maximum TC of 65 K for 6% Mn concentration could be achieved (cf. ref 14).
