Gerhard Klimeck is a German-American scientist and author in the field of nanotechnology. He is a fellow of the Institute of Physics (IOP), a fellow of the American Physical Society (APS), and a fellow of IEEE. He is the Reilly Director of the Center for Predictive Materials and Devices (c-PRIMED), the Director of nanoHUB, the Network for Computational Nanotechnology at Purdue University, and a Professor of Electrical and Computer Engineering. He guides the technical developments and strategies of which annually serves over 330,000 users worldwide with online simulations, tutorials, and seminars.


Klimeck received his Ph.D. in 1994 from Purdue University where he studied electron transport through quantum dots, resonant tunneling diodes and 2-D electron gases. His German electrical engineering degree (Dipl.-Ing.) in 1990 from Ruhr University Bochum was concerned with the study of laser noise propagation.


Klimeck's research interest is in the modeling of nanoelectronic devices, parallel cluster computing, genetic algorithms, and parallel image processing. He has been driving the development of the Nanoelectronic Modeling Tool NEMO since 1994. Klimeck was the Technical Group Supervisor of the High Performance Computing Group and a Principal Scientist at the NASA Jet Propulsion Laboratory, California Institute of Technology. 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, Klimeck developed the Nanoelectronic Modeling Tool (NEMO 3-D) for multi-million atom simulations. NEMO 1-D was the first quantitative simulation tool for resonant tunneling diodes and 1D heterostructures. NEMO 3-D was the first multi-million atom electronic structure code and has been used to quantitatively model optical properties of self-assembled quantum dots, disordered Si/SiGe systems, and single impurities in silicon. NEMO is based on the representation of the nanoelectronic device with atomistic empirical tight-binding. Quantitative device modeling was demonstrated without any material parameter adjustments, just by entry of geometrical structure parameters. At Purdue his group is developing a new simulation engine that combines the NEMO 1-D and NEMO 3-D capabilities into new codes entitled OMEN and NEMO5. NEMO 1-D was demonstrated to scale up to 23,000 parallel processors, NEMO 3-D was demonstrated to scale to 8,192 processors, and OMEN was demonstrated to scale to 222,720 processors.
