Hi Crimsonhen, It is a question of working on the right side of the peak (for noncontact) vs the left side of the peak (for tapping). To be more precise, in what is sometimes referred to as non-contact mode in ambient conditions, the drive frequency is set on the right side of the peak at a location where the amplitude has decreased by some fraction

Hi Alberto, Yes, Kelvin probe microscopy can tell you differences in electrostatic potential. With some assumptions you can deduce workfunction values. And yes, on a MultiMode with NanoScope IIID this mode is available. But please do not hesitate to elaborate on your question so I can better understand what you are asking. Best, Thomas

If you are interested in imaging the nanotubes on graphite, you can take a small amount, put it into a strong, volatile organic solvent like chloroform, and sonicate at high power for several minutes to break up the clumps and create a suspension. Very little nanotube material is needed. If you can tell that the suspension is slightly darkened compared

The lines are Cr, like the pads. The lines are like intedigitated fingers, so when you scan across them, there is an alternation of a line connected to the right pad and subsequent line connected to the opposite pad. And when you connect the wires to a DC voltage source and scan across the fingers in surface potential microscopy mode (Kelvin Probe Force

I think the combination of AFM with Raman is very interesting and there are good reasons why tip-enhanced Raman scattering, despite some challenges, has been a hot research topic in recent years. Below are a few thoughts on its benefits and challenges, please let me know in the forum or offline ( tmueller@veeco.com ) if this is useful and if you have
