Three-Dimensional Photonic Crystals
out of 5 stars
11 Feb 2008 | | Contributor(s):: Minghao Qi
A photonic crystal (PhCs) is typically a composite of a high-dielectric-constant material (e.g. Si) and a low-constant one (e.g. SiO2 or air), arranged periodically in space. Two dimensional examples include a hexagonal lattice of air holes drilled in a Si slab, or a set of Si rods at square...
Multiphase Gallium Nitride Nanowires and Nanocircuits
04 Feb 2008 | | Contributor(s):: Virginia M. Ayres
Catalyst-free vapor-solid nanowire growth, a newly described method for the production of nanowires compatible with a wide variety of semiconductor materials, has been used to produce novel multiphase zinc-blende/wurtzite gallium nitride nanowires. Orientation relation-ships within the multiphase...

Electrons in Two Dimensions: Quantum Corrals and Semiconductor Microstructures
04 Dec 2007 | | Contributor(s):: Eric J. Heller
The images generated by a scanning tunneling microscope are iconic. Some of the most famous are Don Eigler’s quantum corrals, which reveal not only the guest atoms on a surface but especially the interference patterns of electrons shuttling back and forth along the surface. To understand the...
Plastic Deformation at Micron and Submicron Scales
28 Nov 2007 | | Contributor(s):: Marisol Koslowski
Most people experiences the way objects plastically deform on a macroscopic scale. From a car crash to the bending of a paper clip plastic deformation occurs in the form of a smooth flow as a response of an applied stress. But due to the constant shrinking on the dimensions of mechanical devices...
Engineering Nanomedical Systems
16 Nov 2007 | | Contributor(s):: James Leary
This tutorial will cover general problems and approaches to the design of engineered nanomedical systems. An example to be covered is the engineering design of programmable multilayered nanoparticles (PMNP) to control a multi-sequence process of targeting to rare cells in-vivo, re-targeting to...
Engineering at the nanometer scale: Is it a new material or a new device?
06 Nov 2007 | | Contributor(s):: Gerhard Klimeck
This seminar will overview NEMO 3D simulation capabilities and its deployment on the nanoHUB as well as an overview of the nanoHUB impact on the community.
HPCW Condor: High Throughput Computing
09 Oct 2007 | | Contributor(s):: Thomas (Tom) Kesler
Condor is a research project of the University of Wisconsin. It offers an environment called "High Throughput Computing" for compute-intensive jobs. Condor can manage a collection of compute nodes and can harness wasted CPU power from otherwise idle workstations of a cluster or desktop. Condor...

Simulating with PETE: Purdue Exploratory Technology Evaluator
25 Sep 2007 | | Contributor(s):: Arijit Raychowdhury
Using PETE one can evaluate any MOSFET like devices or any New Devices in terms of performance on Benchmark circuits. The input to the tool can be in terms of typical MOSFET parameters or in terms of I-V and C-V tables. The Benchmark circuits include minimum sized inverter, nand chain, norchain,...
Scientific Ethics and the Signs of Voodoo Science
24 Sep 2007 |
Until recently, the issue of research ethics had not been a subject of explicit discussion within the Physics community. Over the past ten years, however, documented cases of scientific fraud have brought this issue to center stage. Looking at case studies, this talk explores examples ranging...
Using Workspaces on nanoHUB.org
24 Aug 2007 | | Contributor(s):: Michael McLennan
One of the most powerful tools on nanoHUB is something we call a workspace, which is a full-featured Linux desktop that you can access any time, any place, from your web browser. Workspaces are fully loaded with the latest nanoHUB software stack, including the Rappture toolkit, Octave, Scilab, a...
The Nano-MOSFET: A brief introduction
17 Aug 2007 | | Contributor(s):: Mark Lundstrom
MOSFET channel lengths are now well below 100nm, and getting smaller, but MOSFETs are still modeled and understood much as they were 30 years ago. Seminal work in the 1960’s laid the foundation for our understanding of the MOSFET, but traditional approaches are based on concepts that lose...
Using Subversion for Source Code Control
14 Aug 2007 | | Contributor(s):: Michael McLennan
If you're developing software, you should be storing your code in a source code control system. The nanoHUB team recommends Subversion, because it is easy to use, open source, and available on Unix/Linux, Windows, MacOSX, and many other systems. Subversion is similar to the popular CVS system...
