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 Book Chapter: “Self-assembly of block copolymers by graphoepitaxy”
We have written a book chapter about the self-assembly of block copolymers by graphoepitaxy. In the fabrication of a desired block copolymer (BCP) nanostructure for a particular application, a key challenge is the control of the BCP microdomain assembly. Graphoepitaxy...
Microsystems Technology Laboratory (MTL) annual report is published
A showcase of MTL's diverse and creative research, this report contains 147 abstracts submitted by 40 research groups. The QNN group's contributions can be found here: Driving Stage for SFQ Circuits using a Single Nanocryotron Modeling Superconducting Nanowire...
New paper: “Infrared transmissometer to measure the thickness of NbN films” published in Applied Optics
We built a transmissometer to determine the thickness of thin films of NbN that are deposited as the starting material for SNSPDs. The transmissometer measures the transmittance of light through NbN thin films, and the thickness of the NbN is found by fitting the...
