Set parameters in the control panels to the following values:
15.2.4 Set Up SPM for Contact AFM
Set up the microscope for contact AFM imaging (The microscope can also be calibrated using
STM; however, this example will utilize contact AFM):
1. In the Other Controls panel set the AFM mode to Contact. Or, select the Microscope >
Profile > Contact Mode > Load button.
2. Set the Scan angle to 0 degrees.
3. Adjust Realtime parameters to obtain a good-quality image (maximum Scan size = 440V).
The Scan rate should be set to a value of 2.44Hz and the Number of samples parameter
should be set at 256.
With the sample engaged, check the scanning line relative to the reference’s features; the scan
should be orthogonal to the pits on the reference. If the reference requires rotation, Withdraw and
rotate the sample to improve orthogonality between sample and scan line. Repeat until features are
oriented orthogonally with the scan frame.
