Spacecraft charging is the accumulation of an electrical charge on orbiting spacecraft induced by the space plasma environment and has harmful effects on the electrical functionality of a spacecraft. This is studied extensively, particularly in the Materials Physics Group (MPG) at Utah State University (USU). During charging studies performed by the MPG, another potentially problematic effect of the space plasma environment on spacecraft was observed: light emanating from the sample undergoing electron beam bombardment. Space-based observatories are one type of spacecraft on which this luminescence may occur. If the luminescence from the material caused by the space plasma is within …

Epitaxial thin film growth and characterization of cuprate oxide insulating materials has been motivated by scientific importance and technological need of these materials for various applications including the nanofabrication of high-Tc trilayer Josephson junction and electronics. For this purpose, we fabricated epitaxial and device-quality (110)-oriented PrBa2(Cu1-xMx)3O7 (x=0.2, M= Ga, Al, Fe, Co, Ni, and Zn) (PBCMO) thin films using excimer pulsed laser deposition technique and conducted systematic studies of the effects of various metals substitution for copper atoms at two different sites of the PrBa2Cu3O7 (PBCO) structure using various characterization techniques including the x-ray diffraction, atomic force microscopy, temperature dependent …
