I am going to use the Focused Ion Beam to cut a graphite lamella, but the surfaces of graphite after cutting turn out to be super rough and form the terraces-like tomography. I am wondering if anyone knows how to address this problem.
I suggest you to have a look at the following papers:

-Drastic effect of shearing on graphite microtexture: attention and application to Earth science
The microtexture of graphite exposed on the polished surface was studied using confocal laser scanning microscopy, laser Raman spectroscopy, and focused ion beam–transmission electron microscopy (FIB–TEM) to elucidate the effect on surface condition and crystallinity of graphite by the polishing process. The polished surface of the graphite was divided into a flat part with no irregularities and a grooved band with a width of
