The frontier of information processing 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 developing nanofabrication technology at the few-nanometer length scale. We use these technologies to push the envelope of what is possible with photonic and electrical devices, focusing in particular on superconductive and free-electron devices. Our research combines electrical engineering, physics, and materials science and helps extend the limits of nanoscale engineering.

New Patent on Self-Assembly Issued to QNN Group Members
A method developed by the QNN Group with collaborators promises a way to make complex two-dimensional patterns by using sparse lithography in combination with self-assembly. Such a technique could be useful for nanofabrication of integrated-circuit patterns, or...
New paper: “Control of zinc oxide nanowire array properties with electron-beam lithography templating for photovoltaic applications” accepted to Nanotechnology
[abstract] We found that electron-beam lithography, a top-down approach, is a suitable prototyping method for templating and controlling hydrothermally-grown ZnO nanowires (NWs). By varying the deposition method of the ZnO seed layer, annealing and template hole...
24-picosecond single-photon timing jitter in saturated SNSPDs – New Paper in IEEE Quantum Electronics
In our new paper, to appear in the IEEE Jornal of Selected Topics in Quantum Electronics (JSTQE), we have demonstrated fully-saturated nanowire single-photon detectors with 24 ps jitter. Furthermore we show an improved fabrication process that allowed us to increase...
