The bound-state resonant tunneling transistor (BSRTT): Fabrication, D.C. I-V characteristics and high-frequency properties
(Elsevier, 1990)
The output characteristics of resonant tunneling transistors with a charge filled bound state quantum well base obtained by a self-consistent solution of Poisson's and Schrodinger's equations show the effect of coupling ...
Measurement of Z0 decays to hadrons, and a precise determination of the number of neutrino species
(Elsevier, 1990-03-08)
We have made a precise measurement of the cross section for e+e--->Z0-->hadrons with the L3 detector at LEP, covering the range from 88.28 to 95.04 GeV. From a fit to the Z0 mass, total width, and the hadronic cross ...
Monte Carlo analysis of the backscattering of radiation from a sphere to a plane
(Elsevier, 1990-02)
A Monte Carlo method is described for computing the backscattering of radiation from a sphere situated above an emitting plane. Numerical results are given and compared with analytic bounds for this problem which were ...
Structure of 11Li in the cluster-orbital shell model for the 9Li + n + n system
(Elsevier, 1990-05-28)
The properties of 11Li are studied in detail in the cluster-orbital shell model assuming the structure of 9Li + n + n. The interactions acting between the constituent particles are carefully determined consistently with ...
An amplifier-discriminator module for very high energy [gamma]-ray astronomy
(Elsevier, 1990-07-15)
An eight-channel amplifier-discriminator module has been developed for processing fast photomultiplier signals from a ground-based [gamma]-ray imaging telescope. The module provides several outputs for recording pulse ...
Some properties of nearly premixed laminar flame propagation along weakly stratified layers in combustible gas mixtures
(Elsevier, 1990-02)
Nearly premixed laminar flame propagation along weakly stratified layers in combustible gas mixtures is examined theoretically in the limit of weak flame stretch, high activation energy, and unity Lewis number. The ...
Far‐infrared absorption spectra measured in InAs/Al0.36Ga0.64Sb quantum wells
(The American Institute of Physics, 1990-05-07)
Far‐infrared absorption spectra have been measured for molecular beam epitaxial InAs/Al0.36Ga0.64Sb multiquantum wells by Fourier transform infrared spectroscopy using light incident normal to the layers. The special band ...
Electronic structure of monoclinic BaBiO3
(The American Institute of Physics, 1990-01-25)
We present the results of photoemission studies of ‘‘valence disordered’’ monoclinic BaBiO3 in the photon energy range 15–120 eV. The line‐shapes of the valence band photoemission spectra and the Ba contributions to the ...
