The ResiScope II is a unique system able to measure AFM resistance over 10 decades with a high sensitivity and resolution. It can be combined with several dynamic modes as MFM/EFM (AC/MAC mode) or KFM single‐pass (AC/MAC III) providing several sample characterization on the same scan area.
The measurement is made by applying a DC bias between the sample and a conductive AFM probe (tip at virtual ground). The tip is scanning in contact mode using the laser deflection for the AFM feedback . As an independent measurement, the ResiScope II measures the sample resistance through the High Performance Amplifier (HPA).

A dual measurement system:
- Resistance measurement
- Current measurement (& IV spectroscopy)
- Compatible with Oscillating mode (Tapping / AC mode )
- Compatible with EFM/MFM or Single-pass KFM
- Resistance 102 ohms to 1012 ohms (10 decades dynamic)
- Output information : R, Log R, Current & I/V Spectroscopy
Principle:
During the measurement, the DSP chooses in real time the best gain to optimize the measurement made by the amplifier module (HPA). This operating condition allows a very high sensitivity on all the range of resistivity at a regular scan speed (AFM) . Contrary to other techniques, the current between the probe and the sample is strongly reduced. This has the result of limiting the local effect of oxidation or electrochemistry and protecting the conductive probe from high current damage.
ResiScope is a smart real-time control of the appropriate ranges to obtain the best measurement (sensitivity and range). It limits the current through tip and sample is limited to prevent any damage. It is more than a simple linear or Log amplifier used for a basic current measurement
ResiscopeTM mode is a mode of contact AFM. A conductive tip saves changes in current and resistance on a wide range with an external amplifier. Curves of current / voltage can be conducted at various locations on the sample. Resistance and conductivity over to 10 decades.
