AFM

Description

Icon AFM incorporates the latest evolution of Bruker’s nanoscale imaging and characterization technologies on a large sample tip-scanning AFM platform. The Icon’s temperature-compensating position sensors render noise levels in the sub-angstroms range for the Z-axis, and angstroms in X-Y. Number of supported techniques and modules able to map different physical as conductivity, capacitance, piezo response, surface potential, magnetic force, etc. Liquid cell give ability not only make SPM measurement in liquid, but also study electrochemical reactions with AFM probe as one of electrodes.

Ask staff for advanced techniques if interested.
