WEEK+OF+DECEMBER+2ND

=**WEEK OF DECEMBER 2ND**=

I tried to see just sample of pure gold with different tips and compre them STM worked really well with first tip but It did not work with second tip actually(It is really ramdom..) But I got some good images with first tip. I will see dibenzo pentacene next monday with this tip and hopefully I can get a image..





I did not go to Notre dame friday becuase I had a SAT test on satueday so I asked becky if I go there on Monday instead. So I will be scanning on monday.

But I researched about STM because I am making a portfolio about STM and I found something I don't understand. []

This is a pure gold that has nothing on the surface. I was scanning pure gold because I wanted to have a good tip first and then start ro scan dibenzo pentancene. As I wrote earlier, dibenzo cannot be scanned itself because it does not have enough conductivity. So it is usually put on gold that has storng conductivity to be scanned. But what I dont understand is how picture like this can come out of the pure gold. Becky said my gold images that I scanned (December 2nd) was pretty good and it is good enough because there is no molecules on the gold and it is pure Maybe I did understand something wrong. I will put the answers tommorrow since I go to the lab tomm.
