  1. Introduction to Scanning Tunneling Microscopy

    20 Apr 2007 | | Contributor(s):: Hyung-Seok Hahm

    This is a 60 second movie clip with an introduction to Scanning Tunneling Microscopy(STM). Design goals are - Give an idea of what STM looks like- Provide an overview of what STM does and how it worksProduced by Imran Sobh and Hyung-Seok HahmAs part of instructional materials by National Center...

  2. Operation of Scannig Tunneling Microscopy

    20 Apr 2007 | | Contributor(s):: Hyung-Seok Hahm

    This is a 60-second movie clip with a narration of how Scanning Tunneling Microscopy(STM) operates. Produced by Eric Meyer, Imran Sobh and Hyung-Seok Hahm Beckman InstituteUniversity of Illinois at Urbana-Champaign As part of instructional materials by National Center for Learning and Teaching in...

  3. 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.

  4. 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.

  5. 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.

  6. 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...

  7. 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.

  8. 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.

  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.
