Talk Title: A Coupled Multiphysics Approach to Modeling Heating in Semiconductor Devices

Abstract: It is estimated that world energy consumption will increase by over 40% from 2012 to 2035. Meeting this energy demand while minimizing the proliferation of greenhouse gases and other toxins is one of society’s key challenges. In recent years, thermal management has emerged as the ultimate bottleneck for improving the performance of consumer/commercial electronics. Controlling device temperature, as well as harnessing waste heat, is crucial to sustaining electronic devices with longer battery life and performance, in addition to potentially reducing our demand on power plants by efficiently using generated electricity. Without proper thermal management, inordinate power dissipation can potentially halt integrated circuit functionality.

For this reason, the development of state-of-the-art simulation models that self-consistently couple the electronic and phonon transport is essential in creating a cycle that pushes designs to have lower carbon footprints and creating environmentally conscious electronics that minimize waste. In this talk, I will highlight my work on electron and thermal transport and its relevance to nanoelectronic devices and materials. We will particularly address issues ranging from transport and modeling issues to power dissipation and energy harvesting. We will draw examples ranging from multi-gate FETs, SONOS memories, tunneling FETs and thermoelectric devices and suggest new directions for improving device efficiency through device and material engineering.


Biography: Mohamed Mohamed received the Ph.D. degree in electrical engineering from the University of Illinois at Urbana-Champaign, Urbana, IL, USA, in 2012. He served as a Research Scientist and Visiting Lecturer with the University of Illinois at Urbana-Champaign. His doctoral dissertation work was performed in the Computational Multiscale Nanostructures group directed by Professor Umberto Ravaioli and has demonstrated self-heating effects in nanoscale silicon MOSFETs through coupled electro-thermal Monte Carlo simulation. His current research interest is primarily on the theory, design, simulation and characterization of energy efficient devices, materials and circuits. He also has a great interest in cyber education and in exploring innovative ways to enhance learning, education, and research. He has developed numerous simulation tools suitable for both research and classroom use hosted on the nanoHUB. He is the recipient of the Ernest Reid Fellowship Award in Electrical Engineering, the Graduate College Dean Fellowship and was listed several times in the UIUC List of Teachers Ranked Excellent.
