Dynamic force microscopy (DFM) phase signals were studied using heterogeneous films of polyvinyl alcohol (PVA). The phase was measured as a function of distance and drive frequency over regions of the film with different dissipative properties. When driving below the free resonance frequency at moderate amplitudes, the tip—sample interaction jumps between… CONTINUE READING
