Metalorganic chemical vapor deposition of InGaAsN using dilute nitrogen trifluoride
The metalorganic chemical vapor deposition of In0.06Ga0.94As1 xNx, with x 1⁄4 0.00–0.02, has been examined using nitrogen trifluoride (NF3) and tertiarybutylarsine. The solid N/V ratio increased linearly with the gas-phase N/V ratio up to a limit of 2.0% nitrogen in the film at a gas N/V 1⁄4 0.35. No further increase in nitrogen content could be achieved at a growth temperature of 550 1C unless...
متن کاملVibrational analysis study of aluminum trifluoride phases.
The vibrational modes of three solid AlF3 phases (alpha, beta, and amorphous high surface area AlF3) are investigated. Calculations have been performed using hybrid exchange correlation functionals to determine the equilibrium geometries and Gamma-point phonon frequencies for the alpha-AlF3 and beta-AlF3 phases. The calculated optical modes are in excellent agreement with experiment. The IR abs...
متن کاملChemical pneumonitis due to exposure to bromine compounds.
A 60-year-old laboratory technician developed pulmonary infiltrates consistent with chemical pneumonitis following accidental exposure to a mixture of hydrogen bromide and phosphorus tribromide. A protracted clinical course ensued consistent with bronchiolitis obliterans. These problems may have been avoided if the potential for subsequent damage had been realized at the time of the initial exp...
متن کاملMean Amplitudes of Vibration of Iodine Trifluoride
Chlorine and bromine trifluoride are two of the best known and well-characterized interhalogen compounds. Information about the corresponding iodine compound is rather scarce, probably due to the fact that it is only stable below -30°C [1] and decomposes easily to form I2 and IF5 [1,2]. The three XF3 species have a T-shaped structure of C2v symmetry, consistent with the presence of 10 electrons...
متن کاملwoman-defined identity: analysis of selected poems of adrienne rich
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
