Nanotechnology Survey with ANTSY

This nanoHUB “topic page” provides an easy access to selected nanoHUB Education Material that is openly accessible and usable by everyone around the world.

We invite you to participate in this open source, interactive educational initiative:

  • Contribute your content by uploading it to the nanoHUB. (See “Contribute Content”) on the nanoHUB mainpage.
  • Provide feedback for the items you use on the nanoHUB through the review system. (Please be explicit and provide constructive feedback.)
  • Let us know when things do not work for you – file a ticket through the nanoHUB “Help” feature on every page
  • Finally, let us know what you are doing and your suggestions improving the nanoHUB by using the “Feedback” section, which you can find under “Support

Thank you for using the nanoHUB, and be sure to share your nanoHUB success stories with us. We like to hear from you, and our sponsors need to know that the nanoHUB is having impact.

Crystal Structures, Lattices, Silicon, Bucky Balls

Crystal Viewer

/site/resources/tools/crystal_viewer/buckyball.jpg /site/resources/tools/crystal_viewer/si.jpg /site/resources/tools/crystal_viewer/fcc.jpg /site/resources/tools/crystal_viewer/bcc.jpg The Crystal Viewer in ANTSY tool enables the interactive visualization different Bravais lattices, and crystal planes, and materials (diamond, Si, InAs, GaAs, graphene, buckyball). It is supported by homework assignment in MS Word and Adobe PDF format.

Exercise: Crystal Lattices

About ANTSY Constituent Tools

The Assembly of Basic Applications for Coordinated Understanding of Semiconductors (ANTSY) has been put together from individual disjoint tools to enable educators and students to have a one-stop-shop in semiconductor education. It therefore benefits tremendously from the hard work that the contributors of the individual tool builders have put into their tools.

As a matter of credit, simulation runs that are performed in the ANTSY tool are also credited to the individual tools, which help the ranking of the individual tools. We do also count the number of usages of the individual tools in the ANTSY tool set, to measure the ANTSY impact and possibly also improve the tool.

In the description above we do not refer to the individual tools since we want to guide the users to the composite ANTSY tool. We cite the individual tools here explicitly so they are being given the appropriate credit and on their rspective tool pages are being linked to this ANTSY topic page.

Crystal Viewer Tool, Piece-Wise Constant Potential Barriers Tool, Periodic Potential Lab, Band Structure Lab, Carrier Statistics Lab, Drift-Diffusion Lab, PN Junction Lab, BJT Lab, MOSCap, and MOSFet.

Additional Reading and Tools

Solar Cells

ADEPT

/site/resources/tools/adept/adept2.png ADEPT is not supported within ANTSY, since it is a research-oriented tool that enables the study of solar cells for various material systems. A Reference Manual and a ADEPT Heterostructure Tutorial are available. The interface is not a simple point-and-click interface as for example the PN junction lab, but simulation commands are entered in a command-like fashion.

MOS Capacitors with Quantum Corrections

Schred

(Image(/images/tool/schred/schred.jpg, 120 class=align-right) failed - File not found) Schred is not formally supported in ANTSY. It contains more advanced quantum mechanical concepts and is a nanoHUB contributed tool. It calculates the envelope wavefunctions and the corresponding bound-state energies in a typical MOS (Metal-Oxide-Semiconductor) or SOS (Semiconductor-Oxide-Semiconductor) structure and a typical SOI structure by solving self-consistently the one-dimensional (1D) Poisson equation and the 1D Schrodinger equation.

Exercises:

madFETs – more Field Effect Transistors

/site/resources/tools/nanomos/nanomos2.gif /site/resources/tools/nanomos/nanomos3.gif /site/resources/tools/nanofet/nanofet2.gif /site/resources/tools/fettoy/1-fettoy.gif /site/resources/tools/fettoy/fettoy1.gif The Field-Effect-Transistor has been proposed and implement in many physical systems, materials, and geometries. A multitude of acronyms have developed around these concepts. The “Many-Acronym-Device-FET” or “madFET” was born. The author of this document was able to trace an attribute to the acronym madFET from Bill Frensley to Herbert Kroemer.

nanoHUB.org hosts a variety of tools that enable the simulation of field effect transisors for a variety of different geometries in a variety of different levels of approximations. There is a madFETs topics page that provides an overview of many of the nanoHUB.org madFET tools.

Technology Computer Aided Design – TCAD

/site/resources/tools/padre/padre.jpg Once students have mastered the basics of semiconductors they may be quite interested in venturing into TCAD. There is a topics page for aTCADlab and associated single aTCADlab tool that assembles various TCAD tools available on the nanoHUB. Process, device, and circuit simulation is represented in aTCADlab.
