=**WEEK OF SEPTEMBER 9TH**=

I and Dr. L tried to see a image through STM and finally we found out what was wrong. We were doing different version of STM and that was the problem. We changed the mode of version and started to try again. Specially today I did some of steps by myself. Changing the tip was somewhat hard by the way. I hope I can change the tip well and see the image next time

I and Dr. L finally found out what was wrong with STM. There was a posibility that there might be some dirts in the machine so we cleaend out with alcohol and tried to run the machine again. Because the condintion wasn't settled down yet, it was impossible to see a perfect image of surface of graphite but as time goes, condition graudually settled down and our image became clear and better.**
