  1. ABACUS—Introduction to Semiconductor Devices

    When we hear the term semiconductor device, we may think first of the transistors in PCs or video game consoles, but transistors are the basic component in all of the electronic devices we use in...

  2. crystal

    Closed | Responses: 0

    How can I determine position of the atoms in the unit cell for a zincblende 110/111 crystal

  3. distorted Miller plane views?

    Open | Responses: 1

    First of all, congratulations for the tool. I’m trying to have my students using it for visualizing crystal surfaces, and wanted to compare the fcc-(100) and bcc-(100). They should both...

  4. I can’t see any images.

    Open | Responses: 1

    The program seems like it runs when I click simulate, but where I’m supposed to be seeing the image all I get is grey. I have access to all of the options on the right hand side.

  5. Can you customize the basis?

    Closed | Responses: 1

    Is there a way to create and visualize a crystal that isn’t already pre-packaged, i.e. use an existing lattice with a custom basis? I want to visualize the crystal structure shown...

  6. how do i see the plane?

  7. about distance

    Closed | Responses: 1

    hii, how can I view the distance between the nearest-neighbour atoms in a bcc lattice?

  8. how do we see other crystal orientations for instance for silicon, (557),?

  9. Crystal Viewer Tool: First-Time User Guide

    01 Jun 2009 | Teaching Materials | Contributor(s): Abhijeet Paul, Benjamin P Haley, Gerhard Klimeck

    This first-time user guide is an introduction to the Crystal Viewer Tool lab. It provides basic definitions, including a definition of crystals. Any suggestions for changes and corrections are...

  10. open surface problem

    Open | Responses: 2

    – I am not convinced that the surfaces that are computed now are actually correct. The bond connections do not look right.

  11. I would like to see a Hexagonal closed packed crystal but where is that? Do you have it?

    Open | Responses: 2

    Thank you for the tool.

  12. In addition to the unit cells, can you also show larger chunks of the crystal

    Open | Responses: 3

    The tool could be dramatically improved if not only the unit cells were shown, but also multiple unit cells to form a larger chunk of the crystal. It would also be great to be able to see...

  13. Bravais lattice viewer shows very small atoms and very long bonds.

    Open | Responses: 2

    The tool could benefit in its visibility if the bonds were made smaller just like the fix that has happened with the graphene lattice, that is now showing properly.

  14. Orthorhombic and Tetragonal unit cells are not properly displayed.

    Open | Responses: 2

    Orthorhombic and Tetragonal unit cells are not properly displayed. They both seem to appear just like cubic cells.

  15. Si and GaAs structure appear to be on different scales or different origins.

    Open | Responses: 2

    It is hard to compare the two materials as the origin is shifted out of the field of view. Can get this get fixed?

  16. graphene unit cell representation shows very small atoms

    Open | Responses: 2

    when the graphene material system is displayed as a unit cell the carbon atoms are really small. In the diamond lattice or the bucky ball that is not the case. Can this get so the atoms are...
