snompy.fdm.eff_pol_n#

fdm.eff_pol_n(sample, A_tip, n, z_tip=None, n_trapz=None, **kwargs)#

Return the effective probe-sample polarizability using the finite dipole model, demodulated at harmonics of the tapping frequency.

Parameters:

samplesnompy.sample.Sample: Object representing a layered sample with a semi-infinite substrate and superstrate.
A_tipfloat: The tapping amplitude of the AFM tip.
nint: The harmonic of the AFM tip tapping frequency at which to demodulate.
z_tipfloat: Height of the tip above the sample.
n_trapzint: The number of intervals used by snompy.demodulate.demod() for the trapezium-method integration.
**kwargsdict, optional: Extra keyword arguments are passed to eff_pol().

Returns:

alpha_eff_ncomplex: Demodulated effective polarizability of the tip and sample.
