The NSIVa thermal tune function is limited in frequency by the data acquisition rate of the NSIVa. The maximum frequency that can be tuned is about 30KHz. The data acquisition rate on the NSV is 50MHz, so it can tune cantilevers up to 2MHz with no problem (assuming that they are not too stiff). The thermal...

I'm trying to demonstrate the tip width of a "1-nm radius" tip by scanning isolated features (bumps or ridges). Does anyone have a favorite specimen that has features 1 nm wide?

How do you know the Modulus value for the reference sample?

What standards ecan be used for PeakForce calibration? What range of moduli can be investigated?

This talk of calibration standards has brought up another question- where to get electrical reference standards for techniques such as scanning spreading resistance (SSRM) or scanning capacitance (SCM)? I'm talking about a stack of layers of known doping concentration and thicknesses of epitaxially...

We calibrate the XYZ scan axes of our AFM using a traceable height and pitch standard made of thermally grown silicon dioxide on silicon. The specimen contains these patterns: 10 um pitch, 2-dimensional array of pits, nominally 200 nm deep 2 um pitch, 1-dimensional array of ridges, same depth as the...
