AFM at KIT |
KARLSRUHE INSTITUTE OF TECHNOLOGY |
Measurement under ambient condition or with Nitrogen atmosphere, for specific applications measurements in liquid are available. Due to clean room location and very massive building, a extremely low noise level is attained to enable sub nm z resolution. Maximum size of a single scan is about 100 by 100µm. this is rarely done as this takes hours to do.
Typical samples are a few mm small and mounted on a carrier to protect the sample and to ease handling. If you consider AFM as a suited technology be aware that the total height variation of your Region of Interest RoI must be less than 5µm including surface roughness, tilt and waviness.

Detection is done via a mechanical lever made from Si or SiN. For micro indentation a steel cantilever is used. Typical size of a cantilever is a fraction of a human hair diameter. So its delicate but on the other hand very sensitive so that forces in the nN range can easily be detected. |
Depending on the Cantilever tip radius, a lateral resolution of <1nm is attained. With cantilever of a suited geometry, the z resolution is in the range of 0,3nm depending on some parameters that have to be discussed |
As mentioned the scan size is approximately 100 by 100µm. Typical scans are up to 20 by 20µm. With sufficient resolution to be superior to optical metrology, a point density of >10points per µm is required. to make full use, a point density of >100points per µm is desirable. That makes single measurements slow. Guess is something like 30 minutes per scan for medium resolution and >60 minutes for HR scans. Positioning is sub µm precise if suited markers are within the scan range. |
Sample can be anything that is flat and at least semi rigid. Gels can be measured, grease with some limitations, and nano particle dust only if the particles adhere to the sample holder. At least if they are fixed. Samples with real 3D surfaces like parabolic mirrors or grids with lenses need to be checked for accessibility. We have some experience in how to mount samples. and for subsequent measurements we offer a carrier system to interchange samples. |
We do not have a vacuum chamber. The lab provides ambient condition with humidity and temperature continuously monitored. We have a heater/cooler stage that allows to cool down to -25 °C and to heat up to 250°C with a nitrogen air flow to avoid oxidization or condensing water on the surface. |
In addition to standard AFM modes, we offer PF-Tapping, PF-KPFM, modes for adhesion measurements and a specific setup to monitor the tip-sample interaction with an additional camera generating movies of the cantilever while in interaction with the surface. This is a valuable source of additional information especially for particle particle or particle fiber interaction analysis.
As we have s automation Software installed, even long time measurements can be performed.
|
AFM measurements are supported by a confocal scanning microscope and a vertical scanning interferometer to generate a more realistic impression of the region of interest. Typically, only if these instruments show that the surface is homogeneous, then the AFM information gained from a very small scan is representing the sample at all. |

Keysight 5100 AFM |
Institut de Ciència de Materials de Barcelona |
Keysight 5100 AFM comprises a scanner of 60 x 60 microns in X / Y and 6 microns in the Z axis. The equipment can use a special liquid cell and controlled environment chamber for conducting scanners at low humidity or in nitrogen. The maximum sample size is 3x3 cm in X / Y and 2 cm thick. The equipment works in the Constant Amplitude Dynamic mode for obtaining topographic images, however Contact mode is also a possibility. The equipment uses an external generator module that can apply in-plane magnetic fields upto + -800 Oe. The equipment is specifically employed to acquired topographic images, having a low noise architecture that allow the acquisition of 500 nm size images. |
