= WEEK OF DECEMBER 14TH = Today, I did my project (milestone map) and realized I forgot something to mention in here. I put the concept of white screen and black screen when fail to scan the sample in my milestone and Becky taught me the difference between two of them. When we fail to scan the sample, the screen usually shows balck or white screen and we can try something different depending on which scrren comes up when fail to scan, -Black screen: when the tip crash the surface -Whtie screen: when there is no connection between the tip and the surface so.. -To check if the tip crashed the surface: black screen -To check if there is conductivity on the sample: white screen -To have a new tip: both black and white -To clean out inside of STM and the cylinder: when the sample doesn't approach

This is from my log book December 14th

when black screen comes up, we might try to check out and try to reapproach it or have a new tip if the tip is so damaged because when the tip is crashed, there is no current so we might not able to see the image and we also might have to check if the sample stick with mica well or if we placed the sample in right way. When white screen comes up, that means, there is no connection between the tip and the sample. We might have made a mistake when we clip the sample or we misplaced (upside down) the sample with the clip.
