Hi, This question very important for me.I have 5% Ti doped ZnO data.It includes not only Zn-K-edge but also Ti-K -edge data.I would like to figure out in following distances and Coordination numbers of them 1)Zn-O 2)Zn-Ti 3)Zn-Zn 4)O-O 5)Ti-Ti 6)Ti-O How can I do them?If you can help to me I will be very glad.Thanks for your help best regards guvenc
Hi Guvenc, It sounds like you need to build some basics. A great place to start is with the Athena and Artemis documentation and the tutorials on www.xafs.org. There are also worked examples using Artemis and Athena installed with the software. Ifeffit\examples\Artemis\ZnO might be an interesting place for you to start. (send a thank you to Scott Calvin) In general all the CN and distances that you metioned below can be determined, except for O-O. That one will take a bit of detective work since you will know the metal-O distances. Good luck, Shelly

Hello all, I am working on analyzing Ge edge EXAFS data of an annealed sample which is likely to be Ge-Te crystallites with some amorphous material at the grain boundary (or perhaps, just Ge-N crystal material at the interface). I do not have any information about the grain size, only possible constituents for the grain and the boundary. Can anyone give me some examples of how Artemis might handle this? Thanks in advance, -- Joseph Washington Research Assistant Department of Physics North Carolina State University 431 Riddick Hall Raleigh, NC 27695-8202 email: jswashin@ncsu.edu

It would help to know what it is that you are after in this analysis. What do you know about the two different kinds of environments? Do you hve endpoints for the crystalline material and the amorphous one? Carlo -- Carlo U.

Hi Joe, Here's an in-progress Artemis file for a system with some broad similarities to the one your describe. Perhaps it will help. Disclaimer: This is not a final fit! --Scott On Oct 17, 2008, at 2:15 PM, Joseph Washington wrote:
