Mythbusting Scientific Knowledge Transfer with nanoHUB.org
26 Oct 2012  Online Presentations  Contributor(s): Gerhard Klimeck
More than 230,000 users in 172 countries annually participate in nanoHUB.org, a science and engineering gateway providing the capability to perform online simulation resources through a web browser without the installation of any software. nanoHUB is an online meeting place for simulation, research, collaboration, teaching, learning and publishing. Over 12,000 users run simulation software from their browser in nanoHUB’s science computing cloud. Cumulatively over 14,000 students in over 700 classes utilized nanoHUB simulations in classrooms and over 1,400 authors referenced nanoHUB in over 850 scientific publications. The platform has spawned nanoHUBU and, in turn, Purdue HUBU, interfaces for online courses that are broadly accessible around the world.

Tight Binding Parameters by DFT mapping
12 Sep 2012  Presentation Materials  Contributor(s): Yaohua Tan, Michael Povolotskyi, Tillmann Christoph Kubis, Yu He, Zhengping Jiang, Timothy Boykin, Gerhard Klimeck
The Empirical Tight Binding(ETB) method is widely used in atomistic device simulations. The reliability of such simulations depends very strongly on the choice of basis sets and the ETB parameters. The traditional way of obtaining the ETB parameters is by fitting to experiment data,or critical theoretical bandedges and symmetries rather than a foundational mapping. A further shortcoming of traditional ETB is the lack of an explicit basis. Alternatively, a DFT mapping process which constructs...
