Hi Deepak, As far as I recall, the Nanoscope-IIIa (V5 series software) does not have a dedciated function to collect specific parameters as a function of time.Which software version are you running exactly? More recent controllers (V) / software, allow one to do this in a couple of ways and at different acquisition rates ('strip-charts', HSDC

Yes, you should be able to use the internal lock-in for PFM measurements (and also create the required AC+DC voltage). Regards, Peter
-
Yes, the Nanoscope-IV controller has the lock-in amplifiers integrated, and does not need an 'Extender' electornics box, as the Nanoscope-III does. Peter

The Nanoscope-IV controller has a built in 'extender' which will allow you to do EFM measurements (or KPFM if you are also interested in doing this mode). No need for any extra equipment. On a Dimension5000, the standard (air) tip holder has an electrical connection to the tip, and can be used for EFM. If a signal access module (SAM) is connected

Hi Sebastien, We never had a heater/cooler module product solution for the D3100-NS3a. We had one for the later versions of the D3100 (with NS4, and closed loop scanner), and this heater/cooler was different than the one you showed in the pictures. I guess you might be able to find a manual from the manufacturer of the temperature controller with an

Hi Annie & Melania, I notice that the triggering to current was switched on, in your parameter settings. If you want the voltage to go through the complete ramp raneg you defined, you should switch off triggering. With triggering ON, the voltage will only ramp until the current reaches the trigger currnet level defined in the parameter settings

Hi Sebastien, The peltier cooling elemeent & temeprature controler you show in the pictures, looks quite different than the product which was offered at any time (by Veeco or Bruker). we have used a few different elements & temeprature controllers over the years, but nothing which resembles what you show (as far as I am aware). Can you tell

Sure. If you are quipped with the C-AFM or TUNA module, and your sample has some conductivity this should be rather straightforward. Make sure to use a cantilever adapted to electrical measurements (solid metal, or metal-coated, for example). Some samples can be a lot harder to get good & repeatable I-V curves, than others. The environment (humidity

Measurign the conductivity of nanowires which are less conductive than their substrate or matrix they are emdedded into, can be difficult. Usually, it is easier to do the reverse: have them on a substrate whcih is less conductive than the actual nanowire. The best success I had is when the nanowires are only partially on a conductive substrate, and

Hi Daragh, In C-AFM (or TUNA), one can operate in 'constant voltage' or 'constant current' mode. 'Constant voltage' is the most common & easiest method, and I strongly recommend you use this. You can select this mode by selecting 'Open' in the feedback mode, or 'disable' (softwrae version dependent). When
