Series Information: Recent economic needs have re-kindled national and global interest in semiconductor devices and created an urgent need for  more semiconductor device engineers and architects. Current students  will need to be trained in the fundamentals of semiconductor devices to meet this growing semiconductor demand. Dr. Gerhard Klimeck will introduce the tools found in the ABACUS tool suite in nanoHUB. He developed these tools to teach his standard semiconductor device class at Purdue University.  These tools include simulations of crystal structures and lattices, bandstructure and band models, bulk semiconductors, PN Junctions, Bipolar Junction Transistors, MOS Capacitors, and MOSFETs.  The ABACUS tool suite is very popular, and has been used by over 15,000 users and in over 350 classes globally. The ABACUS group page highlights various features and animations.

The objective of this recitation series is to enable faculty to enhance existing or new semiconductor classes with interactive simulations. Simulations and animations can immerse students into "what if" scenarios and engage them in more active forms of learning, including explorations used in homework assignments and design projects.

Abstract:In the seventh session, Dr. Klimeck will give a brief overview of ABACUS and demonstrate the MOSFET Lab. Students can experiment with the classical scaling of a traditional 2D MOSFET. Shortening the gate length will deteriorate the device performance and raise the leakage current. Students can also explore double gate MOSFETs which will have improved performance compared to the standard 2D MOSFET. Various effects due to oxide thickness, gate workfunction, doping and doping profiles can be examined. Also material properties such as minority carrier lifetimes can be explored. MOSFET-Lab is powered by the industrial tool PADRE which was used at Bell Labs to design transistors.

Speaker Bio: Dr. Gerhard Klimeck is a 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.
