WEEK+OF+NOVEMBER+11TH

=**WEEK OF NOVEMBER 11TH**=

Today I tried to get an image for gold but could not get the image for it. First time I really did not connect the gold and clip each other because I did not know I had to but they arent connected each other, there is not conductivity so cannot get the image. So I tried agaain with connecting the two. And there was a conductivity this time but could not get the image still I rinsed it off with athanol and tried again and it still did not work. I satisfied all the requirements like sharp enough tip with new taped surface etc.. but still did not work

11-13-09 On friday, I spent time with Becky and sean to talk about STM rather than scanning the sample. It was really helpful and increased my knowledge about STM -Quantom physics: Related to very small things ex)electrons -This was when we talked about how does tip allows us to see the surface -This is about constant height method and liquild scanning



-difference between AFM and STM -My goal of project
