LiDAR, which stands for Light Detection and Ranging, serves as a remote measurementtechnique for studying atmospheric properties, such as gas and particle concentration, aswell as wind speed [23]. The detectors employed in such measurements play a crucial rolein determining factors such as resolution, maximum range, and acquisition time. Supercondu...
For cosmic microwave background (CMB) polarization observations, calibration of detector polarization angles is essential. We have developed a fully remote controlled calibration system with a sparse wire grid that reflects linearly polarized light along the wire direction. The new feature is a remote-controlled system for regular calibration, whic...
Pulsed filtered cathodic arc deposition involves formation of energetic multiply charged metal ions, which help to form dense, adherent, and macroparticle-free thin films. Ions possess not only significant kinetic energy, but also potential energy primarily due to their charge, which for cathodic arc plasmas is usually greater than one. While the e...
Filtered cathodic vacuum arc (FCVA) is a promising technique for synthesizing extremely thin carbon films exhibiting highly tetrahedral (sp3) carbon atom hybridization. However, most FCVA studies are for incident ions impinging perpendicular to the substrate surface. In this study, the effects of the ion incidence angle on the thickness, structure,...
Thin polymer or oxide films are ubiquitous components in many devices, including membranes for filtration or electrodes in electrochemical energy storage. High energy electron or x-ray probes for microscopy and spectroscopy are useful to characterize and understand these materials. However, irreversible damage by the probe radiation remains a chall...
Molybdenum disulfide (MoS2) is a popular lamellar material with desirable properties who's form, and function can vary widely, from particles to monolayer/μm thick films and applications in semiconductors to aerospace lubricants and many more. Physical vapor deposition (PVD) is commonly used to produce dense, conformal micron thick MoS2 coatings, b...
Robust, nanoscale light-emitting devices are attractive for emerging photonic and quantum engineering applications. However, conventional approaches suffer from fabrication challenges or lack the potential to address individual nanostructures, such as quantum dots. In this paper, we present a device that can produce electrically driven light emissi...
