ResiScopeResiScope II – Electrical characterization

The ResiScope II is a unique system able to measure 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).

ResiScope Principle




Organic Solar Cell sample – 5µm scan

Semiconductor :

SRAM memory – 50µm scan


Allow first AC mode imaging / KFM single-pass and Resiscope measurement on the same scan area.

Oxyde characterization:

Local Oxydation Nanolithography (LON) – 5µm scan

LON patterns obtained on a 10nm thick titanium layer deposited onto alumina substrate. The resistance value inside the closed patterns shows in which experimental conditions  the oxydation of the full thickness of the film is achieved. Courtesy of A. Perez – ICMAB / CSIC – Barcelona (Spain).
