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...

[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...

[preprint] [supp. info.] We reported that the superconducting properties scale universally close to the superconducting-to-insulating transition in thin films. This universal behavior was found useful not only for the fundamental understanding of superconductivity...

We design and fabricate superconducting nanowire single photon detectors (SNSPDs). SNSPDs are appropriate for many applications because they have low jitter, a fast reset time and good sensitivity to infrared light. Thus, we are working on several research projects to...
