Selforganization is a powerful tool for information technology. Different kinds of semiconductor wires have already been grown by this technique but their applications to nanostructured electronic devices is still in the beginning. We have contacted single GaN-whiskers by Ti-contacts fabricated by ebeam-lithography. Measurements of acoustoelectric current transport through these selforganized quantum wires will be presented. There a surface acoustic wave is launched on a piezoelectric substrate and the goal is to transport single electrons one by one through the three-terminal device.
