Mechanical properties characterization in a quantitative way

As an expert in force measurements JPK provides a complete set of methods to characterize mechanical properties. Especially for very soft or delicate samples or for samples under external load we have the right solution. JPK's QI™ mode with its linear Z-movement and a full set of quantitative data in every pixel allow the extraction of quantitative data such as elasticity, adhesion, dissipation, chemical forces or conductivity. The automated large z-adjustment is developed for swelling samples or with a rough topography. The enhanced data analysis capabilities - especially for modulus calculation with its variety of selectable models - is a great benefit.

Enhanced material properties mapping

KPM on SRAM EFM on SRAM CAFM on CU conduct layer The characterization of electrical, electromechanical or magnetic sample properties was always a difficult task especially on loosely attached, brittle or soft samples. The enhanced QI™-Advanced mode capabilities make these easy and straight forward. The new system comes with a new Conductive AFM and Kelvin Probe (KPM) module with enclosed volume for a controlled gas environment of the sample. To make the story complete the NanoWizard® 4a system comes with enhanced Piezo-Response (PFM) AFM and electrochemistry options.
