Re: Stiffness measurement

Thank you for your answers. Is the QNM mode an additional software? Does it require special tips? I m also a bit concerned as my polymer has a very low Young's modulus (15-100KPa) and as far as I understood, the QNM measurements have to be carried out in contact mode and not tapping mode. Is this the case? Thanks!

Stiffness measurement

Hello Is it possible to perform stiffness measurements of a polymer using standard AFM? I ve got a Multimode veeco with only SCM and CAFM modules. DO I need extra modules?

Re: IV curve

Hello Peter, yes I do have a CAFM module but I am having issues visualizing the I-V curve as my Nanoscope version seems to be very different from the manual I ve got. Ramp and Mode in my Nanoscope appear to have less options. I had a go but I cannot visualize a plot current (Y axis) vs voltage (X axis) Regards, Daniela

IV curve

Hello Has anyone measured IV curve using a AFM multimode?
