Investigation of hybrid nanostructures using AFM/STM based on tuning fork sensors — •Inshad Jum’h, Viatcheslav Dremov, Yuri Koval, and Paul Müller — Department of Physics and Interdisciplinary Center for Molecular Materials (ICMM), Universität Erlangen-Nürnberg

We present a combination of non-contact AFM and STM using a sharp etched metal tip and a quartz tuning fork as the force sensor. This method has proven to be stable at ambient conditions and provides high-resolution images of topography, conductivity, force gradient and dissipated power simultaneously. This is suitable for conductive, partially conductive and nonconductive materials. In this work, we study a variety of nanostructures and map the conductivity of various hybrid materials. We present our recent results for the graphitized layer of polymer surfaces modified by low energy ion beam irradiation. We demonstrate the possibility to study composite materials based on few layered graphite (FLG) using this method.
