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
Standard ORCA module is capable of measuring currents from ~1 pA to 20 nA.
Dual Gain ORCA uses two separate amplifiers for an even wider current range, from ~1 pA to 10 µA
