Abstract

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. 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 popular ABACUS tool suite 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.

During the recitation series, Dr. Klimeck will introduce ABACUS and each of the seven tools, giving a brief tool overview, transition into working with several sample simulations/materials, share the resources for the tool from nanoHUB (including the tools and materials needed to easily integrate these resources into new and existing coursework) and wrap up each recitation with an open Q&A session.

Bio

Gerhard Klimeck 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 transistors. He was a winner of a 2020 R&D 100 Award for his nanoHUB work: Making Data and Simulations Pervasive.
