Is there a rule of thumb in tip selection for PFT-QNM (peakforce tapping and quantitative nanomechanical measurements) toward reliable mechanical property measurements?
-
The short answer is yes. Electric force microscopy (EFM) and Kelvin probe force microscopy (KPFM) can be either done in a two-pass lift-mode or in a single-pass dual ac frequency mode. Both EFM/KPFM can be done with Peakfroce tapping mode in the two-pass fashion, with the 1st pass using Peakforce tapping for topography, and 2nd pass collecting EFM/SKPFM

Veeco offers ECAFM mode on the following AFM platforms: Multimode, Enviroscope and Innova. There is an electrochemical cell particualrly designed for each system to accomodates the sample, be it cathode materials or else, and counter and reference electrode. They are provided with Universal Bipotentiostat or VersistatIII. You can also use a 3rd party
