Hi friends,
I have a question about the tip ´OTESPA´.
Right now I use it for Kelvin Probe Microscopy measurements. As you know, the tip for KP measurement should be conductive. When I check the details of tip ´OTESPA´, it only says the back side of cantilever is coated with Al.
Does this type´s tip have the Al coating also on the front side( I mean the side with the tip on)? Can I use this kind of tip for Kelvin probe measurement?
Thanks a lot!
No, there is no tip coating on OTESPA probes. The Al coating is backside only for better reflectivity.
MESP or SCM-PIT probes are commonly used for KPFM. If you like the visible apex tip feature of the OTESPA probes, then you might also check out the OSCM-PT probes.
Details for each can be found at Bruker Probes.

Thank you very much Ben! It helps a lot. I have the SCM-PIT tip for conductive- AFM measurements. I can also use it for KPFM.
