At the nanometer scale the concepts of device and material meet and a new device is really a new material and vice versa. While atomistic device representation is novel to device physicists who typically deal in effective mass models, the concept of finite devices that are not infinitely periodic is novel in the semiconductor materials modeling community. NEMO 3-D bridges the gap and enables electronic structure simulations of quantum dots, quantum wells, nanowires, and impurities. Electronic structure simulations of systems 52 million atoms have been demonstrated.
To truly have impact on the research, experimental and educational efforts of the community, relevant tools must be put into the hands of experimentalists and educators. NEMO 3-D can engage both educators and advanced researchers, utilizing a single open source code. An educational version has been released on nanoHUB.org. Over 646 users ran over 4,800 simulations in the quantum dot lab in the past 12 months.
nanoHUB.org is operated by the Network for Computational Nanotechnology (NCN). 26,100 users gained information on the nanoHUB in the 12 months leading to Sept. 2007. Over 5,900 users have launched over 226,000 simulations.
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.
