Hello,I would like to hear your advice in interpreting what is shown in the images below. They were made at 0.1 micron in contact mode, in 256, 512 and 1024 lines, fromleft to right, respectively, on the polished surface of some carbonaceous rock.Apparently, there is a surface rippling as resolution increases, and I don't know how to interpret this, owing that, even at the lowest resolution shown, the separation among scan lines is commensurable with interatomic distance.
Best regards and thank you very much.
Hi lgc,
When you scan the same (or similar) area in Tapping Mode, what do you get?
Stefan
Thanks, Stefan. The waviness is not there.
Hard to say what the reason is but you may have some low frequency noise coupling into your system that the lock-in used in tapping mode simply filters out. Check that your air table is floating properly and/or active vibration working, that there are no pumps running next to the system. Did you change anything on your system or the room lately?
