|Roughness measurement can be done in both Contact, Tapping and ScanAsyst mode. We recommend '''ScanAsyst mode''' because of less chance of (non-uniform) deformation of the sample and less tip wear - and because of ease of use. However it also works fine in tapping mode.
|Roughness measurement can be done in both Contact, Tapping and ScanAsyst mode. We recommend '''Tapping mode''' or '''ScanAsyst mode.''' Tapping mode works fine for hard samples as silicon, metals and so on. ScanAsyst mode is recommended for soft samples, soft polymer, cells and the like because of less chance of (non-uniform) deformation of the sample and less tip wear. ScanAsyst is easier use but tapping mode is less sensitive to the tip wear.
|For Topographic measurements with no steep/abrupt steps we also recommend '''ScanAsyst mode''' due to less chance of (non-uniform) deformation of the sample and less tip wear - and because of ease of use. We also recommend '''Tapping mode''' because we experience less problems when the tip end is slightly broken.  
|For Topographic measurements with no steep/abrupt steps we also recommend '''Tapping mode''' on most samples. Only on very soft samples (e.g. cells) we recommend ''ScanAsyst'' due to less chance of (non-uniform) deformation of the sample - or if you need QNM data. We mainly recommend '''Tapping mode''' because we experience less problems when the tip end is slightly broken.  
|For Steep/abrupt steps but no high aspect ratio structures we still recommend '''Tapping mode''' or '''ScanAsyst mode" .  
|For Steep/abrupt steps but no high aspect ratio structures we still recommend '''Tapping mode''' unless you need need QNM data.  
|For High aspect ratio measurements we recommend Tapping mode. We do not have experience with ScanAsyst therefore we recommend '''Tapping mode'''.
|For High aspect ratio measurements we recommend Tapping mode. We do not have experience with ScanAsyst therefore we recommend '''Tapping mode'''. This requires special probes. You can buy this probes for both Tapping mode and ScanAsyst. They are at the moment (sep-2025) more expensive for ScanAsyst mode.
|For large scan areas where you prioritize to scan fast then you can use '''contact mode'''. Here you can scan with scan rate of up to 2.43 Hz

=Evaluation of used probes=
=Evaluation of used probes=
This evaluation was done to know if the tip end of the ScanAsyst probes was typically dirty or broken when we got bad images. If it was dirty, maybe we could find a way to clean it. If it was broken off we needed to replace it. It turned out it was in most cases broken.
