How does Resiscope III work?
ResiScope™ III is an advanced module for Atomic Force Microscopy (AFM) that enables high-precision electrical measurements at the nanoscale. Here's an overview of its working principle:
-
Conductive Probe:
A conductive AFM tip is used to scan the sample surface.
The tip acts as one electrode, while the sample acts as the other. -
Voltage Application:
A DC bias voltage is applied between the tip and the sample. -
Current Measurement:
As the tip scans across the surface, it measures the current flowing between the tip and the sample. The current range can be from 100 fA to 1 mA. -
Resistance Calculation:
Using the applied voltage and measured current, the system calculates the local resistance. The resistance range covered is from 10² to 10¹² ohms. -
Fast Auto-Ranging:
A fast processor-driven auto-ranging system allows for real-time adjustment of the measurement range. This enables accurate measurements across a wide range of conductivities without manual intervention. -
Current Limit-Protective Resistance:
Current limitation helps to minimize undesired current-related effects like local oxidation or bimetallic effect. -
Simultaneous Resistance/Current/Topography:
While measuring the topography, the system simultaneously captures resistance and current data. This enables comprehensive correlation between physical and electrical properties. -
Compatible with All AFM Modes:
ResiScope III is compatible with all AFM modes such as EFM/MFM and standard KFM. Notably compatible with: PFM/ResiScope simultaneously to define real piezo/ferroelectric domains. Contact mode, oscillating modes, and Soft-IC mode for quantitative electrical measurements on soft samples -
Data Processing and Visualization:
The collected data is processed in real-time to create high-resolution maps of current and resistance. These maps can be overlaid with topography data for integrated analysis. -
Environmental Control:
Measurements can be performed in air, controlled atmospheres, and with temperature control.
Advanced capabilities demonstrated in applications like VO₂ under temperature variation.
The unique design of ResiScope III allows for unprecedented sensitivity and range in electrical measurements, making it a powerful tool for nanoscale electrical characterization across a wide range of materials and applications.
