On November 26th 2019 the Aachen Graphene & 2D Materials Center, featuring two IEEE Distinguished Lectures and the kickoff meeting of the ULTIMOS2 project took place. The lectures were given by Prof. Tibor Grasser and Dr. Frank Schwierz within the framework of the IEEE Distinguished Lecturer Program of the Electron Devices Society (EDS). 60 attendees visited the event in Aachen at the Physikzentrum.
Prof. Grasser is the head of the Institute for Microelectronic at TU Wien, and an expert in the characterization and modelling of electronic devices, including those based on 2D materials. He gave a lecture on the recent achievement from his group “CaF2 Insulators for Ultrascaled 2D Field Effect Transistors” by demonstrating that calcium fluoride (CaF2) can serve as ultrathin gate insulator for 2D devices.
Dr. Schwierz, a Privatdozent and Head of the RF & Nano Device Research Group at the Technische Universitaet Ilmenau, gave a lecture on “2D Electronics – Opportunities and Challenges”. His research is focused on novel device and material concepts for future electronics with his present interest in two-dimensional (2D) electronic materials.
After the lectures, the eventful day continued by the kick-off meeting of the project ULTIMOS2 (Ultimate Scaling and Performance Potential of MoS2 Metal Oxide Semiconductor Field Effect Transistors). ULTIMOS2 is a project funded by the DFG, which builds on the complementary expertise’s of Prof. Grasser, Dr. Schwierz and Prof. Max Lemme (AMO GmbH & RWTH Aachen University) in the fabrication, characterization and modelling of 2D electronic devices. The scope of the project is to give a sound assessment of the actual potential and limitations of MoS2field effect transistors, by gaining a deep understanding of their physics, their scaling behavior and their process integration.
