ResiScope™ & C-AFM
A comparative 80x80 µm scan of a polymer battery sample reveals ResiScope's significant advantages over traditional Conductive AFM:
-
Enhanced Visualization: ResiScope provides superior imaging of highly conductive areas, offering a more accurate conductivity map.
-
Elimination of Artifacts: Unlike Conductive AFM, ResiScope avoids slope effects from surface charging or tip-sample interactions, ensuring data accuracy.
-
Wider Measurement Range: ResiScope's 10-decade bandwidth captures both low and high conductivity features precisely, outperforming Conductive AFM's limited range.
-
Consistent Performance: ResiScope maintains reliable results without the capacitive discharge effects observed in Conductive AFM after scanning highly conductive regions.
-
Comprehensive Characterization: ResiScope's high sensitivity and precision make it the superior tool for thorough electrical characterization of complex materials like polymer batteries.
In summary, ResiScope offers more accurate, comprehensive, and reliable electrical measurements, particularly crucial for advanced materials research and development.
