Dear all, I need to study quartz samples in fluid environment in order to obtain tip-sample adhesion data, where the tip is functionalized with alkanes. My problem is the PeakForce QNM calibration. Shall I calibrate with the functionalized or the bare tip ? Shall I calibrate in fluid or in air ? With the relative or the absolute method ? Thank you,

Dear All, I am trying to use SECPM in Constant Height Mode, but I cannot find any documentation. No problem for Constant Potential Mode and Spectroscopic Mode but I have no information about Constant Height Mode. I use a Nanoscope V with an Universal Bipotentiostat and a MM with a SECPM Head. Any help about this issue would be greatly appreciated. Thank

Hi Thomas, I think that I should use HOPG as a reference material ( 4.6 eV ) and use KPM to have a value of CPD ( between HOPG and PtIr5 tip ). Then, using the same parameters of KPM, I calculate CPD of the sample ( for example Al or ITO ). Now I could have the workfunction of the sample, using the two CPD. Is it correct ? Thank you, Alberto

Hi All, what' s the better way to have the workfunction value of a sample using KPM ? ( Multimode Nanoscope IIID ). Thanks for your suggestions, Alberto

What do you think about the possibility to combine AFM and TERS (tip enhanced Raman scattering) ? Thank you, alberto
