The software is now available at the link found in the note once again. Thanks for bringing this to my attention! --Bede

Hi Jerome, Please see the other post as Joop notes. It seems that you are not the only one that has lost their calibration lately. The two different ETRs are calculated at different distances from the tip apex (there are parameters in the analysis view, so you can control the distances). You should figure out roughly how much penetration you have (how

Hi Scott, Did you recently upgrade your software or system? The thermal tune gains are stored in a file called "system.par". If you have not changed hardware, you may be able to snag the correct calibration values out of the old system.par file found in the directory with the z.exe file (usually in D:\Program Files\Nanoscope\....). Look for

Be sure to place the alpha source in direct line-of-sight to the probe. I often use a piece of tape to attach it directly to the scan head. Good luck! --Bede

Hi Fosterrn Static charge could definitely be an issue, especially in winter when everything is dried out by heating systems. What type of probes are you using? are they conductive? Also, how conductive is the Si? Is it doped? We often use radioactive alpha sources to help eliminate static charge -- they are available from photography stores, but you

Hi Moritz, As you noticed, the NSMatlabExamples program relys on DLLs that are installed with Nanoscope Analysis. Nanoscope Analysis and the DLLs are only available for windows, so you will not be able to use that method if you must stick with your Mac. It is still possible to read the binary PFC file from Matlab, but you will have to parse the header

Hi Singh, This problem occurs when the system is attempting to excite the cantilever with enough drive amplitude to reach the target response amplitude that you have set (or was set by the workspace) in the Autotune window. There are a few reasons this might occur: The autotune frequency range is set incorrectly (so that it does not cover the cantilever

Hi Benoit, There is currently no way to display the fits on the curves in FV mode, but you can export the individual curves to make Force Curves and then use the force curve fitting to do the fit and display the result plotted on the same graph with the data. --Bede

In soft tapping you start with a small free amplitude (Afree) and you use a relatively large setpoint to free amplitude ratio (Asp/Afree as large as possible, but usually greater than about 90%). Note that Afree should be measured within a few um of the sample since the cantilever is damped during the approach by air confined between the cantilever

If the deflection sensitivity measured on a hard sample (Si, SiOx, etc.) is around 67nm/V, you should not have to reduce the defl sens so much (and you shouldn't believe numbers taken with such a low defl sens). Try adjusting the limits... --Bede
