Nanowires and Nanocrystals for Nanotechnology

Google Tech Talks
September 12, 2006

Yi Cui is an istant professor in the Materials Science and Engineering Department at Stanford University. He is a recipient of the Technology Review World Top 100 Young Innovator Award. He received his PhD degree from Harvard University working with Prof. Charles Lieber. He received his B.S. degree from Univ of Science and Technology of China.

Nanowires and nanocrystals represent important nanomaterials with one-dimensional and zero-dimensional morphology, respectively. Here I will give an overview on the research about how these nanomaterials impact the critical applications in faster transistors, smaller nonvolatile memory devices, efficient…

    A few years ago, two parents went out for dinner. A few hours later, the babysitter was calling to ask if she could cover up the clown statue in the kids’ room, the father said,”Take the kids and get out of the house. We’ll call the police, we don’t have a clown statue.” The “clown statue” is really a killer that escaped from jail. If you don’t post this letter on to 10 videos tonight, the clown will be in your bed at 3:00 am with a chainsaw in his hand(SORRY BOUT SPAM THIS REALLY FREAKS ME)

    The terms I really can’t wrap my mind around are “one-dimensional and zero-dimensional morphology”. What do these terms mean?

    I think when people …
    I think when people talk of nanowires they think of them as one-dimensional (having only length). And that the mentioned Quantum Dots (QDs) are the zero-dimensional objects.

    ah, gotcha. that makes sense. Thanks.

    Very interesting.
    It will be interesting to see how this topic of research plays out over the next few decades.

    Every subatomic particle that we know of has at least four dimensions, and the inability of man to measure them shouldn’t redefine yet another term. But don’t surprised about high levels of junk science from all sides. This presentation even referred to protein as a species.

    “Zero-dimensional” …
    “Zero-dimensional” is a convenient label and may not be strictly accurate but facilitates communication in the same way that you would talk about a pencil lead or kleenex rather than pencil compressed graphite paste or paper tissue for the nose respectively. I believe the Professor used species in its strict technical, chemical sense to refer to a chemical entity rather than in its biological sense referring to a collection of biological entities with similar biological characteristics.

    Thnaks for the explanation. In another post I mentioned that redefining terms is problematic, at best. Case closed.

    It refers to the possible movement of the electrons. In a QD the electrons are trapped in all three dimensions due to the nano size of the QD. This physics is a consequence of the geometry though.
