Thread: Scanning Tunneling Electron Microscopes

I am reserching Scanning Tunneling Electron Microscopes, what are pro's and con's of them?

any help would be appreciated, as i am very confused about it all :?

The pro's are many.

The con's are:
- slow throughput
- delicate (tips always seem to break or collect residue)
- resolution is limited by the radius of the tip end
- ability to discern steep sample topography is limited by the tip aspect ratio and the tip end shape (flared tip can be better in this case)
- tips are expensive!

ok, thanks alot for your help. What are a few of the pro's?

I'm Sorry but i think this is a type of cheating. RA

no it isnt cheating its being sensible you stupid mellon. you've done the same in another post, go get your own ideas! or cant you do that? (note to everyone else:mellon got fired from his old job because he turned up at 7.00 when his rotor said 17.00)...how can anyone be that stupid

You have a good point.

It is very easy to research what are the advantages of a particular technique. Google can be your friend. Or a library.

The disadvantages of a technique are often hard to find or know. That's why I responded.
