Description

100 amps of electricity crackle in a vacuum chamber, creating a spark that transforms carbon vapor into tiny structures. Depending on the conditions, these structures can be shaped like little, 60-atom soccer balls, or like rolled-up tubes of atoms, arranged in a chicken-wire pattern, with rounded ends. These tiny, carbon nanotubes, discovered by Sumio Iijima at NEC labs in 1991, have amazing properties. They are 100 times stronger than steel, but weigh only one-sixth as much. They are incredibly resilient under physical stress; even when kinked to a 120-degree angle, they will bounce back to their original form, undamaged. And they can carry electrical current at levels that would vaporize ordinary copper wires.

  2. Quantum Dots

    Online Presentations | 21 Jul 2005 | Contributor(s):: Gerhard Klimeck

    Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such, they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application...

  4. A New Terahertz Heterodyne Detector Based on Single-Walled Carbon Nanotubes

    Online Presentations | 27 Jul 2005 | Contributor(s):: Sigfrid Yngvesson

    We present non-invasive methods for improving the sensitivity of label-free biosensors that offer the advantage of rapid and real-time detection but suffer from relatively low sensitivity. We present detection of cancer markers using the Quartz Crystal Microbalance and demonstrate that 2...

  7. Moore's Law Forever?

    Online Presentations | 13 Jul 2005 | Contributor(s):: Mark Lundstrom

    This talk covers the big technological changes in the 20th and 21st century that were correctly predicted by Gordon Moore in 1965. Moore's Law states that the number of transistors on a silicon chip doubles every technology generation. In 1960s terms that meant every 12 months and currently...

    Online Presentations | 15 Jul 2005 | Contributor(s):: Timothy D. Sands

    What is a quantum dot? What is a nanowire? What is a nanotube? Why are these 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,...

  9. Nanodevices: A Bottom-up View

    Online Presentations | 13 Jun 2005 | Contributor(s):: Supriyo Datta

    It is common to differentiate between two ways of building a nanodevice: a top-down approach where we start from something big and chisel out what we want and a bottom-up approach where we start from something small like atoms or molecules and assemble what we want.
