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.
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.
Fabrication of a MOSFET within a Microprocessor
out of 5 stars
16 Nov 2005 |
This resource depicts the step-by-step process by which the transistors of an integrated circuit are made.
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!
How Semiconductors and Transistors Work
20 Nov 2005 |
This animation shows how semiconductor crystals work and how they are used to make transistor switches.
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.
Molecular Beam Epitaxy
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.
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.
Nanomanufacturing: Top-Down and Bottom-Up
Martin presents an overview of nanomanufacturing techniques, explaining the difference between top-down and bottom-up approaches.
Scanning Electron Microscope
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.
Scanning Probe Microscope Operation
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...
Scanning Probe Microscope Piezoelectric Crystals
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.
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.
What is a Nanometer?
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.
