  • DMT modulus channel

    Dear all, I am having difficulty figuring out why there is a difference in the modulus obtained from the DMT modulus channel which is in GPa order from that calculated from the HSDC files which turns out to be in MPa order by using the herztian fit. I would really appreciate If there is anyone who can help me solve this issue. Another question is regarding

  • HELP needed in Young's modulus (YM) measurements...

    Dear AFM users, During the YM measurements (currently im using multimode and I have hard samples) several things came up and could not exactly figure out how to handle them: 1) I tried to use the point and shoot function but the ramp and capture was not active can someone who knows how to deal this or has experienced this before please inform me how

  • Re: Sample roughness and appropriate probe...

    Thank you Bede for your suggestions. our system was upgraded so I am new with PF-QNM I'm still in the process of learning the system and any shortcuts available. New things keep coming up during measurements but I am grateful for the topics in this forum they have helped alot...

  • Re: Sample roughness and appropriate probe...

    Dear Bede, Thank you for your response. I have not looked into the stiffness of the samples yet, so that may be a starting point for me. The roughness values were previously obtained from profilometry measurements and not during the scanning. From what you mentioned about your measurements what method can you suggest for obtaining the elastic modulus

  • Re: Cantilever selection for measuring adhesion force

    This may be a bit out of the topic but I would also like to inquire what suggestions you may have for measurements of elastic modulus for ceramic samples with roughness of 0.4-2 microns.. Thank you

    Dear Andrea, My samples are ceramic and they are hard I guess that's why ScanAsyst Air probe could not work out. Best, Mariam

  • Sample roughness and appropriate probe...

    Dear AFM users, I have samples which have roughnesses from 0.5 to 2 microns and I am interested in obtaining their elastic modulus using the peak force QNM. I tried to use the scanAsyst probe but from the roughness the tip broke before I could get any measurements done...could any one suggest what type of probe that would be effficient for this particular

  • Re: Analysis for Force curves using Nanoscope Analysis (Dimension Edge)

    Hi, I think first of all you need to update your deflection sensitivity; After calibration you should have obtained a deflection sensitivity and also deformation sensitivity then use these values before you export your force curves from the hsdc file after this then you can use the indentation to calculate your modulus. For Indentation calculation you
