In particular, CNTs can be a metallic or semiconducting depending on the way in which the carbon atoms are arranged in the CNT walls. The purpose of this learning module is to familiarize students with the basic concepts associated with CNT electronic properties. It begins with a pre-test to assess initial student knowledge of the topic, followed by a presentation and reading material on the electronic properties of CNTs. This is followed by some exercises that utilize the CNTbands tool on the nanoHUB for computing key electronic properties of CNTs. Finally, a post-test is administered to determine the degree to which the module assisted in student learning of the fundamental concepts associated with the electronic properties of CNTs. http://www.merlot.org/merlot/viewMaterial.htm?id=85510 The purpose of this learning module is to introduce students to some fundamental concepts in Nanofluidics. The module includes a pretest (without keys), a presentation, reading materials on Nanofluidics, links to the REBO simulation tool on the nanoHUB along with necessary instructions for running the simulation, and a quiz that includes keys and feedback. http://www.merlot.org/merlot/viewMaterial.htm?id=85484 Learn the basics of PN junction theory. Analyze step junctions and linearly-graded junctions both analytically and numerically. See how the depletion region gives rise to a built-in voltage, and also affects the capacitance under AC analysis. Study DC current-voltage characteristics, including both the ideal behavior and corrections for generation/recombination current in non-ideal diodes. http://www.merlot.org/merlot/viewMaterial.htm?id=85482 Rappture is the Rapid APPlication infrastrucTURE, a toolkit that you can use to accelerate the development of scientific simulation tools. Scientists developing a code are often led astray by all of the elements surrounding their code. They end up developing their own command language for input, their own format for output, their own graphics for visualization, their own user interface, and so forth. Solutions vary wildly from tool to tool, with very little regard for human factors engineering, so the resulting tools are often difficult for anyone but the original author to use. http://www.merlot.org/merlot/viewMaterial.htm?id=85481 This learning module is an introduction to the theory ballistic nanotransistors. No transistor is fully ballistic, but analyzing nanotransistors by neglecting scattering processes provides new insights into the performance and limits of nanoscale MOSFETs. This learning module introduces the basic theory and shows how it can be applied to current problems in device research. The concepts are illustrated by exercises that make use of live simulations with the program, FETToy. http://www.merlot.org/merlot/viewMaterial.htm?id=85509 This learning module teaches the basic concepts of molecular conduction. It starts with an introduction to the theory by Supriyo Datta, followed by a review of experimental results. Then, it walks you through a series of hands-on examples and exercises, where you can simulate molecular conduction right in your web browser! Finish up by taking a quiz to test your understanding of the concepts. http://www.merlot.org/merlot/viewMaterial.htm?id=86717 NOISE (New Outlooks In Science & Engineering) is a UK-wide campaign funded by the Engineering & Physical Sciences Research Council (EPSRC). Initiated in 2000, it aims to raise awareness of science and engineering among young people. The site contains links to other interesting sites, upcoming events, blogs and cool jobs all related to the science and engineering community.
