    I am well Philippe. Thanks for your note and good to hear from you again. I hope all is well with you. Agreed, the figure is a schematic and as such makes it the trade off between detail and simplicity. To address your questions let me refer you to the Application Note on Peak Force QNM.

    I don’t have any papers on this, but believe it is a daunting task to try to extract viscoelasticity from Tapping or Phase. This is challenging because the phase signal is a non-linear function of set point but more so because the phase signal is the mix of multiple sample interaction contributions including viscoelasticity but also plasticity
