Charge transport mesasurements performed with an ultra compact multi-tip STM — •Marcus Blab, Vasily Cherepanov, Peter Coenen, and Bert Voigtländer — Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, 52425 Jülich, Germany, and JARA-Fundamentals of Future Information Technology

An ultra compact 4-tip STM was constructed in order to investigate the charge transport through nanostructures. Examples for systems which can be studied with such a microscope include nanowires, graphene and nanoscale semiconductor devices. The instrument diameter of 50 mm leads to high mechanical stability and low thermal drift. The heart of this multi tip STM is the ultra compact Koala Drive nanopositioner. We will show the characteristics of this new machine like drift and noise. Furthermore first measurements at test samples and lithographic structured samples of nanowires will be presented.
