Dynamics of AFM cantilevers

Hi everyone,

I am looking for papers on the dynamics of AFM cantilevers in contact with non linear material samples. In particular, I am interested in forced armonic vibrations of the catinlevers.

I have seen many papers on intermittent contact (or tapping) which has a number of additional problems w.r.t. the contact mode.

Many thanks for the help.
