IBM Measures Force Required To Move Atoms

Tjeerd writes "IBM scientists, in collaboration with the University of Regensburg in Germany, are the first ever to measure the force it takes to move individual atoms on a surface. This fundamental measurement provides important information for designing future atomic-scale devices: computer chips, miniaturized storage devices, and more." I've attached a video if you are interested.

    They've been the first (only?) company to construct their logo with individual atoms - and that was in 1990. Looks like they don't give up researching the basics, despite turning more and more into a consulting/support company, not the big iron provider they've always been.

    Dude, what are you doing at slashdot? This is a nerd site, not a greedhead site. This advances human knowlege, who gives a damn if it ever makes a profit?

    Does the Hubble bring profit? No. Do earth based telescopes bring anyone profit? No. Should they? Not as a primary function. There are more important things in life than money and profits!

    There was a beautiful sunrise this morning. Although nobody made any money off of it, I greatly profited by the experience. Mankind greatly profits by knowing how much force is required to move an atom, whether IBM makes any money from the exersize or not.

    Go back to the bank to worship your little green god and stop trolling us nerds.

    Well, yes, they did move atoms with precision in 1989 (from TFA), but moving things and measuring the force required are two different things. If you know the exact forces you can automate the process much more effectively as no manual checking is needed.

    IBM measures force required to move a cobalt atom over a platinum (and copper) surface. I would gather that the force for different atoms is minutely different, as well as whatever friction or molecular interactions b/w the atom and surface material.

    ...the force required to move a cobalt atom over a smooth platinum surface is 210 piconewtons, while moving a cobalt atom over a copper surface takes only 17 piconewtons
    An almost factor of 13 between the two surfaces. Maybe due to the valence electron difference between the two materials, but it is right that this is important for nano-technology, something about which I know less than physics and chemistry.

    Because when this story was there a week or two ago, 90% of the comments were stupid jokes.

    This is a really interesting part of surface science, which in itself is more important than people give it credit for.
    The force to move that atom meassured _directly_ is something new, that will also allow more educated guess on the dynamics of self-assembling layers.

    To illustrate a point: All those nice pictures like shoing "IBM" in atoms are usually done on a nice surface (Pt-111), and cooled down to helium temperatures. At room temperatures, those atoms just around on a timescale faster than you can meassure a picture.
    This is also (or even more) the case when creating thin layers on a substrate, where there are lots of different ways for layers to grow (some substrate material combination first grow "islands", others form a single layer, and islands later, others grow layer by layer). This is hard to detect in situ (a LEED picture only shows that much...). So anything we know about those forces helps understanding this behaviour.

    And yeah, about practical applications: Everything from solar cells (organic ones have _very thin_ layers in their CIGGSE sandwitch) to lithography (dielectric mirrors for EUV-lithography is a hot topic)

    The intro to the video has "people patents projects" it is almost scary to see that patents is that entrenched in their business plans. Although at the same time IBM has done a lot to increase the research and knowledge in the whole nano-tech field. When I was a tech in a lab the prof running the lab told me that most of the time when there was some barrier that no one could cross in the nano-tech field IBM would throw a ton of money at it and solve the problem. So it is nice to see they are still working on solving problems and advancing the field.

    They've been the first (only?) company to construct their logo with individual atoms -

    To be perfectly fair to other companies, IBM has a very simple logo. It is also black and white. Now that we can finally see atoms in color, other companies can get in on that action.

    If you could make circuits like that, it would be really interesting, although useless. For instance, I can imagine an Air where the CPU (at the atomic level) looked like the Apple logo tesselated again and again.

    Some questions are expensive to answer. For example, how much is it worth to teleport materials at the speed of light?

    If you want to teleport something, you have to take the source material apart, atom by atom and rebuild it elsewhere, atom by atom. Can we do that? No, because we don't know how to tear something apart atom by atom, identify the atoms we've just torn off the source, transmit the x,y,z coordinates along with the atom type and put the same kind of atom at the translated x,y,z coordinates yet. We're on the way though.

    Initially, it'll be inanimate objects. UPS is currently capitalized at $75 Billion so there's a little bit of money to be made moving stuff around. Of course, why move stuff instead of just fab as needed? Once you've torn something apart, you know what you need to make as many copies as you want.

      If we ever get to the point where we can disassemble a person and rebuild people quickly enough then you're talking several orders of magnitude of value more. Take snapshots of yourself when you're especially healthy and use those as restore points for yourself. Add some patching software that merges your experiences which are stored as atom arrangements in your brain since your last snapshot and you have immortality. How much is that worth? Don't like your nose? There'll be body shops that use the photoshop equivalent to touch up your features. How much is that worth? Want a bigger cock? Not a problem. Whatever you can imagine, and then some could be possible.

    Will any of the above ever happen? Who knows? What we do know is it won't happen if we aren't willing to pay to answer the 'little' questions. Like how much force is needed to move an atom.

    Such a frivolous waste of money! I can't stand it when people do things that will never see a profit! That's what I tell my kids whenever they ask me to take them to the cinema or go to an amusement park or other silly wasteful things like that. They should be setting up lemonade stands on the roadside during their summer vacation.

    Why just the other day I told my wife not to have sex with me because it's a complete waste of time and energy, which could be better spent packing coins into little rolls to change at the bank. Speaking of which, semen is quite valuable at sperm banks, so blowing it elsewhere is just shooting money out the window.

    Wasteful people >:(
