Standard Functions
Contact Mode Lateral Force Mode (LFM)
This mode creates an image of By detecting the amount of twist in the
displacement in the sample height cantilever during contact mode scanning,
direction by scanning the sample surface an image can be created from

Force curves can be measured as well. sample and cantilever.
Dynamic Mode Force Modulation Mode
This mode vibrates the cantilever near its This mode vibrates the sample at constant
resonant frequency. Since the amplitude amplitude and frequency during contact
changes as the cantilever approaches the mode scanning. The cantilever response is
sample, a sample height displacement detected by separating it into its
image can be created by moving the probe amplitude and phase components. This

Phase Mode
This mode detects the phase shift delay in
the cantilever vibration during dynamic
mode scanning. This allows creating an
image of differences in sample surface
properties.

Magnetic Force Mode (MFM) voltage can be programmed to allow
scanning according to a program.
This mode scans the sample with a
magnetic tipped cantilever kept at a
constant distance from the sample. An
image can be created from magnetic
information of the sample surface
obtained by detecting the magnetic
force from the magnetic leakage eld. N S N S
