| Abstract | What is a quantum dot? What is a nanowire? What is a nanotube? Why are they interesting and what are their potential applications? How are they made? This presentation is intended to begin to answer these questions while introducing some fundamental concepts such as wave-particle duality, quantum confinement, the electronic structure of solids, and the relationship between size and properties in nanomaterials. A more recent version of this talk titled "Nanotubes and Nanowires: One-dimensional Materials" is available.

Timothy gives the listener everything he wants know. I had much difficulty understanding even the basics of quantum mechanics before I went through this presentation.

This is easily my favorite lecture yet on the Nanohub website. I think it should be the first lecture in the Nanotechnology 101 series. It begins strong, introducing quantum dots and nanowires/tubes, and I especially like that this presentation explains *why* the nanoscale is so physically significant (lattice vibrations, how far electrons travel before scatter, possibility of defect free structures, etc). Far too many lectures just rely on "smaller is better" without giving any insight into the radical possibilities presented by this new technology. More than just being more physically accurate, I feel this approach allows the student to wonder and imagine new nano-ideas right off the bat. Your presentation on semiconductors versus conductors and insulators went down very smoothly and transitions nicely to electron particle/wave duality, which again flows perfectly into quantum confinement. The lecture doesn't go too far into the examples at the end, but it does a fine job of touching many different bases. As an introductory lecture, I think that the presentation is almost perfect. More so than any other lecture I've seen (which is a lot), this explains "why" instead of just giving dispencing fact after fact. I appreciate the time you devoted to each topic, and I feel that I took more from this lecture than any other. The new understanding I've gained of conduction and quantum confinement will be especially useful in upcoming projects. Please keep up the excellent work. My only criticism is that the speaker doesn't restate questions from the audience. As it is very difficult to hear the people asking questions, this detracts from the Q&A sections throughout the lecture.
