Hi, Fenny, You can send me your files and screen shot of your settings so that I can advise, you should have my email :) For average deformation, just a rough estimation will work, you can just use section analysis to get an idea of mean deformation. For bearing depth analysis, you need to set bearing area to be 50% under area percent (beside input

Hi Dejan, Since you are using tapping mode, you might need to calibrate the amplitude sensitivity instead of deflection sensitivity. You can either use TM amplitude or TM deflection plot to do so and I guess you already have got amplitude-distance curve so you can just update the amplitude sensitivity by linear fitting of the repulsive part of the curve

Hi, Chris, the help file of the software is pretty nicely self explained and demonstrated, if you still have some questions, you can post them here or contact a Bruker application.

Hi, nhung, Your problems are not difficult to address, just some tricks will help, but to get the full understanding of the answer (not only the tricks but also their mechanism), you'd better contact a local bruker application expert and spend some time together to solve your problem more efficiently and clearly. In case you need contact information

Hi, Dmitry, the classic one I read at beginning was Atomic Force Microscopy in Cell Biology, Volume 68 (Methods in Cell Biology) http://books.google.com/books?id=gL9MpmcpwOUC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false and a good series of books are 'Applied Scanning Probe Methods' published since

Hi, if correctly calibrated, contrasst in deformation channel should also appear in modulus channel, usless your deflection sensitivity was not calibrated accurately. I guess you can roughly correlate the measured deformation to the thickness of your oil patches if you have very high indentation force to fully penetrate the oil layer. But a quantitative

Hi, Albert, You can find 'X Axis' in the control panel for plotting depth histogram and just simply switch it to 'Absolute' instead of default 'Relative', then you can get 'height histogram' you are referring to. LA

Hi, Fangfang, I would like to take a look at your raw data on QNM of the two samples and tip check result if you have. You can send to my email at ang.li@bruker-nano.com LA

sorry, Fangfang, I made a mistake in my last reply, you can check mean value in roughness analysis for the average modulus.

Hi, Fangfang, You should not flatten modulus image, it will change your data. To get average, you can simply use roughness function to get Rq and Ra for your analysis. LA
