معرفی
Joerg Appenzeller is the Barry M. and Patricia L. Epstein Professor of Electrical and Computer Engineering at Purdue University, and Scientific Director of the Nanoelectronics Group in the Birck Nanotechnology Center. His research focuses on nanoelectronics, 2D materials (e.g., MoS₂, WSe₂, black phosphorus), and their applications in advanced transistors, spintronics, and quantum sensing. He leads efforts in device fabrication, interface engineering, and low-power electronics, with contributions to probabilistic computing and resistive random-access memory (RRAM) technologies.
Appenzeller's work integrates material science, quantum physics, and electrical engineering to address challenges in scaling semiconductor devices and enhancing their performance. His lab develops novel transistor architectures, explores defect-engineered 2D materials, and investigates spin-based stochastic systems for energy-efficient computing. He has pioneered studies on vertical 2D heterostructures, phase transition-based memories, and ultra-scaled FETs with record performance metrics.
Key research directions include:
- Optimizing contacts and interfaces in 2D FETs to minimize resistance and hysteresis
- Developing spintronics platforms for tunable random number generation and neuromorphic circuits
- Advancing quantum sensing techniques using NV centers in diamond for nanoscale characterization
- Creating scalable fabrication methods for quasi-2D semimetals and layered chalcogenide devices
His interdisciplinary approach bridges fundamental material science with applied engineering, aiming to enable next-generation electronics and computing paradigms. The Birck Nanotechnology Center provides state-of-the-art facilities for his cutting-edge research in nanoelectronics and nanomaterials.
