Schematic illustration of the stripe geometry a as well as of the corresponding RHEED patterns b developed during buffer growth. Due to the {11n} sidewall facettation of the stripes with an inclination α relative to the in plane [110] direction, facet spots appear in the RHEED patterns that are tilted by α with respect to the specular spot
