Tutorial 1: Advanced Characterization of Nanostructures Using a Nanomanipulator in Charged Particle Beam Microscopes
Time: Monday, August 18, 2008, 8:30am to 11:30am
Presenter: Taylor Cavanah, Zyvex
Nanomanipulators have been integral in bridging the gap between our macroscale world and the nanoscale world. They are becoming increasingly popular in research universities around the world and have contributed to the latest developments in the microelectronics industry. As the world grows smaller, the need for and usage for nanomanipulators will continue to increase.
In this tutorial you will learn how nanomanipulation works, how it works alongside charged particle beam imaging technology, and how it integrates other electrical and mechanical hardware to characterize at the nanoscale. Examples will be presented on the manipulation and/or characterization of nanowires, nanotubes, nanospheres, nanodevices, SRAM transistors, DRAM transistors, functional bitcells, metal lines, and thin films. The tutorial will cover applications spanning from electrical test to mechanical test to thermal test. The tutorial will conclude with a look toward the future of nanomanipulation and the challenges faced as nanoscale science progresses.

Tutorial 2: Introduction to nanoHUB.org – online simulation and more
Time: Monday, August 18, 2008, 1:30pm to 4:30pm
Presenter: Gerhard Klimeck, Ph.D., Purdue University
The nanoHUB is a freely available, rich, web-based resource for research, education, and collaboration in nanotechnology. The nanoHUB hosts over 945 resources which will help the user learn about nanotechnology, including Online Presentations, Courses, Learning Modules, Podcasts, Animations, Teaching Materials, and more. Most importantly, the nanoHUB offers simulation tools which can be accessed from the web browser; so one can not only learn about but also simulate nanotechnology devices. The nanoHUB provides a collaboration environment via Workspaces, Online meetings, and User groups. Resources come from 463 contributors in the nanoscience community, and are used by thousands of users from over 180 countries around the world. Most of our users come from academic institutions and use nanoHUB as part of their research and educational activities. But we also have users from the national labs and from industry. Most of our applications are devoted to nanoelectronics right now reaching from semiconductor device models to nanowire simulations. Over 6,200 users have run over 270,000 simulations and over 60,000 users have utilized the nanoHUB in the past 12 months. We define a user as a logged-in, self-identified individual, an IP address that is using interactive seminar content for more than 15 minutes, or an IP address that downloads (not just views) a content item. nanoHUB is receiving 3 – 5 million web sites hits monthly.
The nanoelectronics simulation tools available on the nanoHUB can address issues in quantum dots, resonant tunneling diodes, carbon nanotubes, PN-junctions, MOS capacitors, MOSFETs, nanowires, ultra-thin-body MOSFETs, finFETs, and others. The nanoHUB simulation facility is different from most other online simulation facilities. The tools are not driven by non-interactive web-forms with static data output, but by a full fledged UNIX application that runs in a user’s browser. Users can interactively setup their numerical experiment, interactively view results, compare different simulation runs, and easily ask “What if?” questions. The tools under the hood can be sophisticated industrial device simulation engines, advanced simulation tools, or simple MatLab® scripts that explore concepts. The user is not bothered with the set-up of complicated arcane input decks, but the tool capabilities are exposed through a graphical user interface that is based on Rappture technology. Within the past 3 years, over 75 simulation tools have been deployed. These tools are supplemented by additional material such as first time user guides and class room material such as homework or project assignments. Collections of tools and class room material are available for example in the “Semiconductor Device Education Material”. Researchers can use the nanoHUB simulation tools to explore design spaces, concepts, or for device optimization. Many of the tools are open source and the source code can be downloaded for inspection, self-installation, and modification. These research uses have resulted in over 216 citations of the nanoHUB in the scholarly research literature.
Gerhard Klimeck is the Associate Director for Technologies of the Network for Computational Nanotechnology at Purdue University and a Professor of Electrical and Computer Engineering since Dec. 2003. He guides http://nanoHUB.org which serves over 58,000 users worldwide with on-line simulation, tutorials, and seminars in the year 2007. He was the Technical Group Supervisor of the High Performance Computing Group and a Principal Scientist at the NASA Jet Propulsion Laboratory. Previously he was a member of technical staff at the Central Research Lab of Texas Instruments where he served as manager and principal architect of the Nanoelectronic Modeling (NEMO 1-D ) program. At JPL and Purdue Gerhard developed the Nanoelectronic Modeling tool (NEMO 3-D ) for multimillion atom simulations. His research interest is in the modeling of nanoelectronic devices, parallel cluster computing, and genetic algorithms. Dr. Klimeck received his Ph.D. in 1994 from Purdue University and his German electrical engineering degree in 1990 from Ruhr-University Bochum. Dr. Klimeck's work is documented in over 180 peer-reviewed publications and over 310 conference presentations. He is a senior member of IEEE and member of APS, HKN and TBP.
Tutorial 3: Molecular-scale Components in Electronic Applications
Time: Monday, August 18, 2008, 1:30pm to 4:30pm
Presenters: Curt A. Richter, Ph.D., NIST

Molecules and molecular architectures hold substantial promise for electronic applications. During the past decade, remarkable progress has been made. Two-terminal molecular rectifiers have been constructed, three-terminal single-molecule transistors demonstrated, and molecular recognition transducers develop. Complex theoretical formalisms have been reduced to tractable algorithms. New molecule-based switching and sensing paradigms have been proposed. In short, the progress has been substantial; the promise of using molecules in electronic systems remains strong.
This tutorial will review the state-of-the-art in the field of molecular electronics, from the making of molecule-containing junction through the measuring of electronic function in those junctions, from modeling molecular conductance through future directions for the field. Subjects to be discussed include self-assembly, theories of molecular conductance, energy-level alignment, and platforms for measuring conductance through molecules.
