3. Quit Auto Tune.
4. Select Back to Image Mode.
5. Engage the AFM and make the necessary adjustments to obtain a good topography (Height)
image on Channel 1.
6. In the Interleave Controls panel set the Lift start height to 0nm, and Lift scan height to
100 nm. (The lift height can later be optimized).
7. Set the remaining Interleave parameters (Setpoint, Drive amplitude, Drive frequency,
Gains) to the main Feedback Controls values.
Note: This can be done by setting the flags to the left of each parameter to “off
(grayed bullets).
8. Set the Channel 2 Data type to Phase and choose Retrace for the scan Line direction on
both Channel 1 and 2 images.
9. In the Interleave Controls panel set Interleave mode to Lift.
Note: For NanoScope software versions 4.23 and lower set Interleave scan to Lift and
switch Interleave mode to Enable in the Interleave Controls panel.
10. Set the Channel 2 Scan line to Interleave to display interleave data. This screen should now
display the cantilever phase change due to electrical force gradients from the sample in the
right image and topography in the left image.
Note: If Analog 2 is being used to apply voltage to the tip or sample, it is
recommended to apply it only during the Interleave line if feasible. Set Analog
2 to the desired voltage in the Interleave Controls panel. In the Feedback
Controls panel set Analog 2 to 0V.
Note: For NanoScope software versions 4.23 and lower: There is no separate
Analog 2 setting available in the Interleave Control panel, so Analog 2 must
be set in the Feedback Controls panel. For more details, refer to EFM
Troubleshooting/Pointers: Section 16.3.
11. Optimize the Lift scan height. For high-resolution, make the Lift scan height as small as
possible without crashing the tip into the surface.
