Welcome to Advanced Nanoelectronics & Nanostructures (ANN) Lab Website!

We are a research group led by Dr. Zafer Mutlu, Assistant Professor of Materials Science and Engineering, with joint appointments in Physics and Electrical & Computer Engineering at the University of Arizona. Our work explores novel materials, physics, and devices to advance computing, telecommunications, sensing, and beyond. Through our research, we aim to tackle today’s challenges, drive technological progress, and develop solutions that shape a better future. Currently, our group is actively working on four fully funded projects. Our primary research focuses on graphene nanoribbon-based (GNR) transistors, where we study charge transport in these low-dimensional materials to develop high-performance, energy-efficient alternatives to silicon-based electronics. We also work on topological acoustic wave devices, designing and fabricating structures that leverage topological physics to precisely control acoustic waves, advancing radio-frequency and sensing technologies by improving efficiency and enabling new functionalities. Another key area of research involves chalcopyrite semiconductors, where we investigate their electronic properties and slow leaching behavior to improve copper extraction while minimizing environmental impact. Additionally, our newest research direction explores low-dimensional materials for thermal management and enhanced functionality in integrated photonics, aiming to optimize heat dissipation and expand the capabilities of next-generation photonic systems. Beyond these core projects, we actively pursue curiosity-driven research, science for science, exploring innovative and unconventional ideas that push the boundaries of materials science and device engineering.
