Alison Chaiken 17:42, 30 September 2005 (UTC): I have only used Veeco's KPFM instrument so it's possible that other vendors have KPFM that work differently. The text of the article is a bit misleading if it is an attempt to describe how Veeco's system works. The specific text I find worrisome is this:[reply]

As the tip (work function: ψtip) contacts the sample (work function: ψsample) electrically, a potential difference (Δψ / q) between the tip and the sample is produced.

In fact, Veeco's method is completely non-contact. This text suggests that contact electrification is taking place, which is not true. In fact, KPFM as implemented by Veeco uses their "lift mode" where the tip flies at a constant height above the surface. I have used 60 nm as the lift height in my measurements, which pretty much guarantees that there's no contact.

Great, please revise the text to make it more accurate. I'm sure most of us have never used KVPMs before, so you probably know better than we do. Anyways, it's a little fishy how the article currently says "electrical contact"; that might mean simply that the tip is close enough to the surface to interact with it, not that it is close enough to the surface to be in mechanical contact.--Conwiktion 01:52, 9 October 2005 (UTC)[reply]

Proposed merge with Scanning Kelvin Probe

[edit]

Page created by a COI-afflicted editor, intended to promote BioLogic in subtle manners. At any case, the difference between SKP and SKPFM is quite less and most of the literature uses the two terms, interchangeably. A reader is far better served to understand the two topics at the same page per WP:NOPAGE. WBGconverse 14:09, 20 June 2019 (UTC)[reply]

I agree the original SKP page looked very much like an ad for BioLogic, but the technique is somewhat distinct from KPFM (and I think there are other manufacturers who produce instruments closer to SKP than KPFM). When I read the KPFM page today, I was very confused about which technique it was describing. Perhaps it could be useful to review this merge or maybe break up the current page into more clear sections for "Contact Mode KPFM", "Non-Contact Mode KPFM" and "Scanning Kelvin Probe" (or maybe Non-Resonant KPFM, but that could be a little misleading?). Not sure if its possible to undo a merge (or if its a good idea)? Ilent2 (talk) 12:11, 5 November 2023 (UTC)[reply]
