Abstract
Dr. Klimeck will give a brief overview of ABACUS and demonstrate the PN Junction Lab. With the PN Junction Lab, students can explore band edge diagrams and charge distributions as a function of bias. They can see how the bands move and how the depletion region narrows and widens. Students can change the doping levels and explore shallow versus wide junctions. Learners with a deeper interest can dive into the effects of minority carrier relaxation times and resistive behavior in realistic devices. The PN Junction Lab is powered “under the hood” with an industrial strength simulation engine that was designed and used at Bell Labs to model and produce a variety of different electronic devices.

Bio
Dr. Gerhard Klimeck is a Chaired Professor of Electrical and Computer Engineering at Purdue University; Director of the Network for Computational Nanotechnology; Reilly Director of the Center for Predictive Materials and Devices. He helped to create nanoHUB.org, the largest virtual nanotechnology user facility serving over 2.0 million global users, annually. Dr. Klimeck is a fellow of the Institute of Physics (IOP), the American Physical Society (APS), the Institute of Electrical and Electronics Engineers (IEEE), the American Association for the Advancement of Science (AAAS), and the German Humboldt Foundation. He has published over 525 printed scientific articles; he has been recognized for his co-invention of a single-atom transistor, quantum mechanical modeling theory, and simulation tools. His NEMO5 software has been used since 2015 at Intel to design nano-scaled design transistors. He was recently awarded a top 100 by R&D for his nanoHUB work - Making simulation and data pervasive.
