Asylum Research recently introduced ORCA, a new module for conductive AFM measurements using the MFP-3D(TM) AFM System. Conductive AFM is a current-sensing technique for electrical characterization of conductivity variations in resistive samples. ORCA allows current measurements in the range of hundreds of femtoamps to nearly a microamp and provides a wide range of current measurement options with near Johnson Noise-limited performance. The ORCA module consists of a specially designed cantilever holder that includes a transimpedance amplifier. The user can choose the gain of the amplifier.
