Using blueDrive and the NanoWorld Arrow UHF AFM tip, it was also possible to simultaneously map the topography and tip-sample stiffness using AM-FM mode (Figure 2). Like Burson et al., a disordered-appearing surface, with length scales similar to those reported in that paper could be seen. Interestingly, these structures were visible with slightly different resolutions with every attempt made. This is a testament to the low noise of the Cypher AFM and to the reliable sharpness of the Arrow UHF cantilevers.
