Quantum Nanostructures and
Nanofabrication Group

Prof. Karl K. Berggren

The frontier of electronic and photonic devices lies in nanoscience and nanotechnology research. At the nanoscale, materials and structures can be engineered to exhibit interesting new properties, some based on quantum mechanical effects. Our research focuses on pushing nanofabrication technology to the few-nanometer length-scale by using charged-particle beams combined with self-assembly. We use the technologies we develop to push the envelope of what is possible with photonic and electrical devices, focusing in particular on the nanowire-based superconductive photodetectors. Our research combines electrical engineering, physics, and materials science and helps push the boundaries of what is considered possible in nanoscale engineering.
