Do you actually have concrete evidence that the hardness of this particular thing is similarly difficult to these other hard things that are regularly accomplished, or is this just "hard things are the same as other things also termed hard"?
My impression is that pushing atoms around and getting them to actually stay where they have been pushed are different things.
- moocowduckquack 13y agoI expect it to be about as difficult as this - http://www.sciencedirect.com/science/article/pii/S1466604901000216 http://www.sciencedirect.com/science/article/pii/S1466604901... - but not quite as difficult as this - http://www.youtube.com/watch?v=oSCX78-8-q0 http://www.youtube.com/watch?v=oSCX78-8-q0 - or this - http://www.youtube.com/watch?v=Pk7yqlTMvp8 http://www.youtube.com/watch?v=Pk7yqlTMvp8
- EdwardCoffin 13y agoYou believe that single atoms of the most reactive element (fluorine) will not be quite as difficult as carbon monoxide molecules [1] to push around? [1] The pixels in the first of the two videos you linked to, according to http://www.research.ibm.com/articles/madewithatoms.shtml#fbid=I5iCfOIIvqF http://www.research.ibm.com/articles/madewithatoms.shtml#fbi...
- moocowduckquack 13y agoI don't believe that you would have to push them around at all in the way that the IBM guys are pushing around those atoms, I put that forward as something that is harder to do. You'd probably start with batch making a ton of very small doped samples and then testing if any have unusually low resistance.
