The ResiScope system for the Nano-Observer atomic force microscope (AFM) is an award-winning instrument for electrical characterization. Resistance measurements ranging over 10 orders of magnitude (from 102 Ohms to 1012 Ohms)  can be performed with the ResiScope. Resistance, log R, current and I/V spectroscopy data can be acquired and displayed.Resistance signal, scan size 1micron, ResiScope mode-AFM map of the electrical resistance of the oxide film grow on stainless steel in high temperature water

Designed for versatility, multiple modes may be performed at the same AFM tip location with no reduction in scan speed. The ResiScope is compatible with several AFM imaging modes, including Contact, Lateral Force Microscopy (LFM), Oscillating (Tapping), Electric Force Microscopy (EFM), Magnetic Force Microscopy (MFM), and High Definition single-pass Kelvin Probe Force Microscopy (HD KFM).

ResiScope mode can be done in contact or oscillating mode. When using the intermittent contact mode, there is no friction and the tip is held at a constant force so soft samples can be quantitatively measured.
