Great picture of the AFM tip!
posted by: vgoss
Here are two images of the AFM tip which were taken by Natalie and Becky using the Digi Scope during the NANOweek Institute - great impromptu idea! The pictures were very timely – they were taken and immediately displayed as the students (a.k.a. teachers) were learning about the AFM tip and cantilever = )
The picture above shows the measured length and width of the cantilever. Picture taken by Natalie W. Here we can estimate that the cantilever is 10 times longer than its width. The tip is the small pale yellow circle at the far edge of the cantilever.
The second image was taken by Becky Q., and it shows a slanted profile which captures both the cantilever and tip – cool illustrative shot! We can see that the length of the tip is the same order of magnitude as the width of the cantilever, which is not obvious in the first image.
