Superconducting MoN thin films prepared by DC reactive magnetron sputtering for nanowire single-photon detectors
Lily Hallett, Ilya Charaev, Akshay Agarwal +4
We present a comprehensive study of molybdenum nitride (MoN) thin film deposition using direct current (DC) reactive magnetron sputtering. We have investigated the effect of variou…
Image-Histogram-based Secondary Electron Counting to Evaluate Detective Quantum Efficiency in SEM
Akshay Agarwal, John Simonaitis, Karl K. Berggren
Scanning electron microscopy is a powerful tool for nanoscale imaging of organic and inorganic materials. An important metric for characterizing the limits of performance of these…
Large-area microwire MoSi single-photon detectors at 1550 nm wavelength
Ilya Charaev, Yukimi Morimoto, Andrew Dane +3
We demonstrate saturated internal detection efficiency at 1550 nm wavelengths for meander-shaped superconducting nanowire single-photon detectors made of 3 nm thick MoSi films with…
Reduced damage in electron microscopy by using interaction-free measurement and conditional re-illumination
Akshay Agarwal, Karl K. Berggren, Vivek Goyal
Interaction-free measurement (IFM) has been proposed as a means of high-resolution, low-damage imaging of radiation-sensitive samples, such as biomolecules and proteins. The basic…
Enhancement of optical response in nanowires by negative-tone PMMA lithography
Ilya Charaev, Andrew Dane, Akshay Agarwal +1
The method of negative-tone-PMMA electron-beam lithography is investigated to improve the performance of nanowire-based superconducting detectors. Using this approach, the supercon…
