  • Re: Sample roughness and appropriate probe...

    Dear Mariam, How stiff (ballpark) is your ceramic sample? When you say the roughness is 0.5-2um what is the scan size that gives you that roughness? If you want to measure the modulus of a stiff sample, you must use a stiff cantilever. Question 1 will allow you to look in the manual and find the recommended probe. However, even with the recommended

  • Re: Cantilever selection for measuring adhesion force

    You should choose a cantilever that is sensitive as possible, but does not cause the deflection measurement to saturate or become non-linear. The force is the spring constant times the deflection sensitivity times the detector voltage (F=K*Sd*V). If we know K for a given probe type and we know the approximate Sd (this depends on probe type, head, microscope
