Powering Next-Gen AI Chips with Quantum-Tunnelling Transistors 💡 Conventional microchips have long been constrained by the "Boltzmann tyranny" — a fundamental physical barrier that caps energy efficiency and holds back high-performance computing. To break through this bottleneck, a research team led by Prof. Jianhua HAO, Head of the Department of Physics and Materials, Chair Professor of Materials Physics and Devices and Associate Director of PolyU-Wuhan Technology and Innovation Research Institute at PolyU — in collaboration with researchers from the National University of Singapore, The Hong Kong University of Science and Technology, Peking University, and the Singapore University of Technology and Design — has engineered a novel quantum-tunnelling field-effect transistor (TFET) using 2D nanomaterials. The landmark findings are now published in the prestigious international scientific journal "Science". 🔬 By replacing thermionic emission with quantum tunnelling, the device drastically cuts switching voltage while overcoming the low-current limitations of earlier TFET designs. Crucially, the team used pulsed laser deposition (PLD) to demonstrate compatibility with standard silicon fabrication, paving the way for the commercial scale-up of ultra-low-power AI chips. Through cross-institutional collaboration, PolyU continues to pioneer semiconductor innovation, offering a scalable blueprint for the future of global microelectronics. 🌐 Learn more in the comments below! #PolyU #PolyUResearch #Semiconductors #TFET #AIChips
