Asylum Research Announces ORCA(TM)-A New Module for Conductive AFM Imaging

June 3, 2004 (Santa Barbara, CA) Asylum Research, a manufacturer of atomic force microscopes (AFMs), introduces a new module, ORCA, for conductive AFM measurements using the MFP-3D(TM) AFM System. Conductive AFM is a powerful 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. Standard values range from 5x107 to 5x109 volts/amp. The cantilever holder is used with conductive AFM probes to make the measurement.

ORCA is ideal for characterizing a variety of materials such as dielectric films, ferro-electric films, nanotubes, or conductive polymers (see attached image example).

Asylum Research manufactures advanced scientific instrumentation, including AFMs/ SPMs (Scanning Probe Microscopes), for nanoscale science and technology. (An AFM/SPM is one of the premier instruments used for measuring surfaces and surface properties at the nanometer level).
