  • Re: Batch processing C-AFM I-V data

    Hi Jörn-Oliver, You can do batch exporting of ramp files to ASCII in either Nanoscope or Nanoscope Analysis by selecting all of the files you want to export (with shift-click or ctrl-click) in the browse view right click to open the contex menu choose Export>ASCII... This will generate a bunch of text files that can be read by Excel or whatever

  • Re: Using high aspect ratio probes

    Additionally, you might want to try dropping the "Engage setpoint" to 0.08V (in the "Other" controls in scan parameter list) and the engage step size to 0.5um (in the general engage parameters). This will help give a softer engage when using stiffer probes with Peak Force Tapping, but you might have problems with false engaging if

  • Re: QNM Questions

    The specific situation that caused us to choose 85% is the sort of long range repulsion or baseline error shown in this curve: This kind of thing is fairly common in fluid (double layer forces). It is a little strange to call it noise, but it is not part of the sample deformation either. If your curves look more normal and you have a jump to contact

  • Re: Question about Poisson coefficient

    Hi Esther, Wikipedia has a nice writeup about Poisson's ratio that would be a good place to start. It is not easy to measure this without a bulk sample. Some methods are: http://www.springerlink.com/content/2481427842138392/ : bulk measurement http://clifton.mech.northwestern.edu/~me381/papers/mechtest/sharpe2.pdf : bulk measurement http://www.springerlink

  • Congratulations to the 2010 Physics Nobel Prize winners

    I'd like to echo Steve's congratulations to this year's Nobel Prize winners in physics, Andre Geim and Konstantin Novoselov at the University of Manchester. You've got to love that their sample prep technique for graphene is now called the "Scotch tape technique". I'm looking forward to all sorts of interesting science

  • Re: Script writing?

    You need support note 394 "Hybrid XYZ SPM Head". Part number 013-394-000. Let me see if I can send you a copy... --Bede

  • Re: Perpendicular converse piezoelectric coefficient (d33) versus applied bias?

    It would really help us be more specific in our response if you could provide the version of Nanoscope that you are using (look under the "Help" menu where it says "About...") and the type of controller that you are using. Thanks! --Bede

  • Re: Anodic Oxidation with Nanoman

    We found that having a native oxide actually resulted in better results than the H-passivation, but it might have to do with the humidity here in Santa Barbara. Humidity, applied bias, tip velocity and surface treatment definitely all play a role in how much oxide you end up getting. --Bede

  • 100steps script sample output of NanoMan Strip chart

    Sample output of NanoMan Strip chart when using 100steps script. This was collected on an Icon with Icon scanner using Nanoscope v8.15.

  • Re: Script writing?

    If you have a Hybrid XYZ head, you should be able to use the PicoForce view to set up a script consisting of linear segments that might work. The PicoForce view is not available for scanners that do not have a Z sensor since open loop Z does not give you accurate positioning during scripting. --Bede
