| Abstract | Future field effect transistors will be on the same length scales as “esoteric” devices such as quantum dots, nanowires, ultra-scaled quantum wells, and resonant tunneling diodes. In those structures the behavior of carriers and their interaction with their environment need to be fundamentally explained at a quantum mechanical level. Modeling efforts that are targeted to enhance the theoretical understanding of these devices are underway worldwide. Most of these device level descriptions utilize an effective mass approach which ignores any details of the atomic granularity. However, the concepts of device and material meet at the nanometer scale. The new device is really a new material and vice versa. A representation of the constituent materials at the atomic resolution is needed to quantitatively model devices with a countable number of atoms. While atomistic representations are novel to device physicists, the concept of finite devices that are not infinitely periodic is novel in the semiconductor materials modeling community. This presentation will provide a perspective of the NEMO 1-D and NEMO 3-D tool developments, their scaling on advanced computational resources up to 23,000 processors, their impact on the understanding of nanoelectronic devices, and the need for continued algorithm work. |
| Biography | 
Dr. Gerhard Klimeck is a Professor of Electrical and Computer Engineering at Purdue University and
serves as the Associate Director for Technologies of the National Science Foundation Network for
Computational Nanotechnology since Dec. 2003. For the NCN he has been directing the replacement of
web-form driven online simulation on www.nanoHUB.org by fully
interactive simulations. The change in technology resulted in a six-fold
growth of simulation user numbers in just over 2 years to over 5,900 annual
users. His research interest is in the quantum mechanical modeling of
electron transport through nanoelectronic devices, parallel computing, and
genetic algorithms. This interest drove the development of NEMO 1-D and
NEMO3-D. Dr. Klimeck received his Ph.D. in 1994 from Purdue
University and his German electrical engineering degree in 1990 from
Ruhr-University Bochum. |
