Week of Oct 19-23

21st of October I went to the lab for 2 hours Today I got to do something different from what I normally do. Usually I scan just plain Au (111), but today (because my sample wasn't ready) I got to scan gold with Octanethiols on the surface. The set up with the laser and the sample holder were all the same other than this change. I took alot of scans, but I didn't really get any great images. I was able to see the chains on the surface, but the images weren't very clear. I was able to make this comparison by looking at several images that Annette has taken in the past; images that I have seen before when I save my images. In addition to using the gold with octanethiols I also had the assignment of showing R how to use Annette's scope and things that you can do to improve you image (I have learned many things and I am still learning ways to improve my scans everytime I go to the lab). The sample that I used was actually a sample that Annette had prepared for herself to scan, but she ended up not using the sample. R had questions about the scanning process and some about the images. I was able to answer many of these questions, however, there were alot of questions I did not know the answers because it was my first time scanning gold with octanethiols on the surface. While it may be some time before I use this type of sample again, I will look up more on Octanethiols and the current research on this topic.

23rd of October I went to the lab for 2 hours
