Animations (1-14 of 14)

  1. Band Structure Lab Demonstration: Bulk Strain

    12 Jun 2009 | | Contributor(s):: Gerhard Klimeck

    This video shows an electronic structure calculation of bulk Si using Band Structure Lab. Several powerful features of this tool are demonstrated.

  2. Center of Excellence on Novel Materials (CENM) Overview Video

    11 Oct 2010 | | Contributor(s):: Pedro Antonio Prieto

    The CENTER OF EXCELLENCE FOR NOVEL MATERIALS (CENM) is part of a high-priority national effort supported primarily by COLCIENCIAS and integrated by 19 recognized multidisciplinary research groups from 10 universities across Columbia.

  3. Fabrication of a MOSFET within a Microprocessor

    16 Nov 2005 |

    This resource depicts the step-by-step process by which the transistors of an integrated circuit are made.

  4. Feasibility of Molecular Manufacturing

    14 Mar 2005 |

    Martin and Laura have an interesting debate about the feasibility of Molecular Manufacturing. Can molecular assemblers be developed to create new materials, new devices, and even macroscopic objects? Find out... If Martin ever wakes up!

  5. How Semiconductors and Transistors Work

    20 Nov 2005 |

    This animation shows how semiconductor crystals work and how they are used to make transistor switches.

  6. In-situ carbon nanotube tensile test

    07 Oct 2011 | | Contributor(s):: Brian Demczyk

    This represents the first in-situ tensile test observed in a transmission electron microscope.

  7. Molecular Beam Epitaxy

    16 Nov 2005 |

    Microelectronic devices are made by repeating two steps: 1) Depositing a thin uniform layer of material; 2) Then using a photographic process to pattern and remove unwanted areas of that layer.

  8. Nano/Bio Connection

    02 Apr 2005 |

    Nanotechnology is not just a topic for physicists, chemists, and engineers. Laura explains the important role of biologists in this field, and shows how they may help provide clues to molecular assembly techniques.

  9. Nanomanufacturing: Top-Down and Bottom-Up

    14 Mar 2005 |

    Martin presents an overview of nanomanufacturing techniques, explaining the difference between top-down and bottom-up approaches.

  10. Scanning Electron Microscope

    16 Nov 2005 |

    This resource describes a scanning electron microscope (SEM). It includes detailed depictions of how the electron beam is focused and used to create hugely magnified images of experimental specimens.

  11. Scanning Probe Microscope Operation

    16 Nov 2005 |

    Scanning Probe Microscopes (SPMs) include Atomic Force Microscopes (AFMs) and Scanning Tunneling Microscopes (STMs or STEMs). They are the only instruments in widespread use that can actually "see" single atoms! You can skim this resource quickly to learn the general concepts of SPMs, or you can...

  12. Scanning Probe Microscope Piezoelectric Crystals

    16 Nov 2005 |

    In this resource we disassemble the piezoelectric assembly of a scanning probe microscope. At its core is a white cylinder of the piezoelectric material. If you look closely, it has a granular texture that reflects the fact that it is actually made up of many small crystals.

  13. Scanning Probe Microscopes

    15 Mar 2005 |

    Laura explains how scanning probe microscopes can be used to create images of small devices, molecules, and even atoms! A large-scale version of the scanning probe microscope is built out of Legos to show the basic principles.

  14. What is a Nanometer?

    02 Apr 2005 |

    Join Laura and Martin on a wild ride through the milliworld and the microworld to reach the nanoworld. Along the way, they discover how small a nanometer truly is.
