Microfabrication of palladium-silver alloy membranes for hydrogen separation [PDF]

, 2003
In this paper, a process for the microfabrication of a wafer-scale palladium-silver alloy membrane (Pd-Ag) is presented. Pd-Ag alloy films containing 23 wt% Ag were prepared by co-sputtering from pure Pd and Ag targets.

A High Quantum Efficiency Narrow-Band UV-B AlGaN p-i-n Photodiode With Polarization Assistance

IEEE Photonics Journal, 2021
We designed and fabricated narrow-band UV-B AlGaN p-i-n photodiodes (PDs) with a full-width at half-maximum (FWHM) of 8 nm by optimizing the Al composition and thickness of the AlGaN layers. To improve the photoelectric response of the narrow-band PDs, a
