The carriers generated in the nanowire by a focused light spot are acoustically transferred to a second location where they recombine. We show that the recombination of the transported carriers occurs in a zinc blende section on top of the predominant wurtzite nanowire. This allows contactless control of the linear polarized emission by SAWs which is governed by the crystal structure. Additional polarization-resolved photoluminescence measurements were performed to investigate spin conservation during transport.application/pdfenghttps://creativecommons.org/licenses/by/2.0/530Charge transportSpin transportGaAsNanowiresSurface acoustic wavesPhotoluminescencePolarizationArticle
