Characterization of arsenic-rich waste slurries generated during gallium arsenide wafer lapping and polishing [PDF]

open access: yes, 2009
The toxicology of gallium arsenide is well established; it is classified by the state of California as a known carcinogen. Consequently, environmental aspects of GaAs wafer manufacture are coming under greater scrutiny, with the cost of waste disposal ...

Short-Baseline Electron Neutrino Disappearance, Tritium Beta Decay and Neutrinoless Double-Beta Decay

open access: yes, 2010
We consider the interpretation of the MiniBooNE low-energy anomaly and the Gallium radioactive source experiments anomaly in terms of short-baseline electron neutrino disappearance in the framework of 3+1 four-neutrino mixing schemes.

Magnetorotational Instability in Liquid Metal Couette Flow

open access: yes, 2002
Despite the importance of the magnetorotational instability (MRI) as a fundamental mechanism for angular momentum transport in magnetized accretion disks, it has yet to be demonstrated in the laboratory.

Determination of Gallium in Rare Earth Ore by Inductively Coupled Plasma-Mass Spectrometry Using Polyurethane Foam Pre-concentration/Separation

open access: yesYankuang ceshi, 2016
Gallium in rare earth ore is commonly determined by Inductively Coupled Plasma-Mass Spectrometry(ICP-MS), but high content of rare earth will result in significant mass spectrum interferences.In this study, Ga in sample solution was absorbed by ...

Defect behavior in electron-irradiated boron- and gallium-doped silicon [PDF]

open access: yes
Production and anneal of defects in electron-irradiated, float-zone silicon solar cells were studied by DLTS. In boron- and gallium-doped, n+-p cells, dominant defects were due to the divacancy, carbon interstitial, and carbon complex.

Radiation damage [PDF]

open access: yes
The radiation damage workshop considered a variety of topics among which were the need for equivalent electron fluences in gallium arsenide, the possibility of 15 percent end-of-life efficiencies for silicon, increasing radiation resistance in gallium ...
