Nature and distribution of electrically active defects in Si‐implanted and lamp‐annealed GaAs
(The American Institute of Physics, 1985-12-01)
The nature and spatial distribution of deep levels arising from defects in device‐quality, Si‐implanted, and lamp‐annealed liquid encapsulated Czochralski GaAs have been investigated. The best activation and mobility values ...
Theory of photoluminescence in quantum wells in the presence of transverse electric field: Monte Carlo approach
(The American Institute of Physics, 1986-04-15)
The Monte Carlo approach is used to study the quasibound electron and hole ground‐state levels in a quantum well in the presence of a transverse electric field. A criteria is developed to ensure that the ground state is a ...
An examination of the cyanide derivative of bovine superoxide dismutase with electron-nuclear double resonance
(Elsevier, 1982-05-21)
The Cu(II) sites of native, azido- and cyano-derivatives of bovine superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) have been examined by electron-nuclear double resonance ENDOR). The ENDOR spectrum ...
Absence of goldstino decoupling in hierarchical superunified models
(Elsevier, 1983-08-25)
It is shown that there exist a class of hierarchical supersymmetric unified models in which the Goldstino field does not decouple from that light states. We illustrate this with an SUN model. The phenomenology and cosmology ...
Efficient algorithms for estimating the width of nearly normal distributions
(Elsevier, 1983-06-15)
Typical physics data samples often conform to Gaussian distributions with admixtures of more slowly varying backgrounds. Under such circumstances the standard deviation is known to be a poor statistical measure of distribution ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Reaction between YBa2Cu3O7−x and water
(The American Institute of Physics, 1989-02-01)
Reaction between water at 80 °C and YBa2Cu3O7−x (0.8<x<0.0) is studied using x‐ray absorption fine structure (EXAFS) and x‐ray diffraction (XRD). Oxygen deficient YBa2Cu3O7−x reacts with water and decomposes into BaCO3, ...
Measurement of upper limits for the decay widths of D*+ and D*0
(Elsevier, 1988-10-06)
Upper limits for the decay widths of the D*+ and D*0 mesons have been measured using data from e+e- annihilations at [radical sign]s=29 GeV obtained with the High Resolution Spectrometer at PEP. We find [Gamma]D*+ c2 at ...
