ORCA™ on Cypher AFMs provides conductive AFM imaging and I-V measurement capabilities. The standard module is capable of measuring currents from ~1 pA to 20 nA. Other current ranges and Dual Gain versions are available.
Powerful current sensing technique for electrical characterization of conductivity variations in resistive samples
Optional amplifiers allow current measurements in the range of hundreds of femtoamps to ten microamps
Dual Gain ORCA uses two separate amplifiers for an even wider current range, from ~1 pA to 10 µA
