Lateral Modulation Ffm Tab - JEOL JSPM-5200 Instructions Manual

5.5.3 Lateral Modulatio
You can perform lateral modulation FFM measurement by additionally installing
optio nal Lock-in Amplifier. When the loc
controller, you have to set the instrument using the software to display the tab window
for lateral modulation FFM measurement.
■ Affixing specimen (for JSPM-5200/JSPM-5700)
In order to observe a lateral modulation FFM image correctly, it is essential to affix the
specimen firmly to the specimen stub using conductive paste instead of using
double-faced tape.
The figure above shows the specimen holder for JSPM-5200.
■ Checking
before approaching
Affix the specimen, adjust the laser and the photodiode, and then perform the coarse
approaching as you perform in AC AFM measurement.
■ Observ
ation of a topography image
Observe a topography image of the specimen surface, and confirm that you can obtain an
optim um image. Then retract the tip.
