Stress-Induced Switching Of Nonlinear Optical-Properties Of Linear-Polymers, Olle Heinonen Jan 1990

Stress-Induced Switching Of Nonlinear Optical-Properties Of Linear-Polymers, Olle Heinonen

Faculty Bibliography 1990s

Replacement of every other hydrogen atom in trans-polyacetylene by other atoms, such as fluorine, results in a simple linear polymer with two carbon atoms per unit cell of the polymer chain. In such polymers, dimerization can be induced or destroyed reversibly by the application of a uniaxial stress. As a consequence, the nonlinear optical properties can be switched dramatically between those of dimerized chains, which have degenerate ground states, and nondimerized chains, which have a nondegenerate ground state.

Room-Temperature Optical-Absorption In Undoped Alpha-Al2o3, M. E. Innocenzi, R. T. Swimm, M. Bass, R. H. French, A. B. Villaverde, M. R. Kokta

Faculty Bibliography 1990s

Optical absorption over a large dynamic range obtained by two different experimental techniques is reported for an undoped α‐Al2 O3 single crystal. Absorption data are presented in two energy ranges: 0.94–3.5 eV and 4.5–8.6 eV. Vacuum ultraviolet (vuv) absorption measurements were performed on three boules of Czochralski‐grown single‐crystal Al2 O3 with differing starting material purities. The initial powder purities were 99.99%, 99.999%, and 99.999999%. In addition to the vuv measurements, calorimetric absorption results obtained in the visible and near‐infrared (ir) are presented. An empirical formula is obtained that provides an estimate of the absorption coefficient from the near‐ir to the …

Modeling The Cutoff Frequency Of Single-Heterojunction Bipolar-Transistors Subjected To High Collector-Layer Current, J. J. Liou, F. A. Lindholm, B. S. Wu Jan 1990

Modeling The Cutoff Frequency Of Single-Heterojunction Bipolar-Transistors Subjected To High Collector-Layer Current, J. J. Liou, F. A. Lindholm, B. S. Wu

Faculty Bibliography 1990s

High current densities in the collector layer reduce the cutoff frequency of heterojunction bipolar transistors. We develop a model based on analytical expressions that describe this reduction. These expressions represent the contributions from each of six regions defined in the output current‐voltage characteristic. The model has parameters determined entirely by device physical makeup. It has no fitting parameters. Its predictions agree well with experimental data taken on two N/p+/n aluminum‐gallium‐arsenide/gallium‐arsenide transistors having abrupt junctions grown by molecular‐beam epitaxy. Because previous models omitted the effects of high current densities, their predictions agree less favorably. The development of …

Effects Of Using The More Accurate Intrinsic Concentration On Bipolar-Transistor Modeling, J. J. Liou, J. S. Yuan, W. W. Wong Jan 1990

Effects Of Using The More Accurate Intrinsic Concentration On Bipolar-Transistor Modeling, J. J. Liou, J. S. Yuan, W. W. Wong

Faculty Bibliography 1990s

A more accurate intrinsic concentration was suggested recently. Discrepancies between using the conventional and the more accurate intrinsic concentrations on bipolar transistor modeling are assessed in this study. Our calculations show that the conventional intrinsic concentration overestimates the collector and base currents by a factor of 1.5 to 2 but affects less severely the steady‐state current gain.

Diffusion Of Color-Centers Generated By 2-Photon Absorption At 532-Nm In Cubic Zirconia, Nastaran Mansour, Kamjou Mansour, E. W. Van Stryland, M. J. Soileau Jan 1990

Diffusion Of Color-Centers Generated By 2-Photon Absorption At 532-Nm In Cubic Zirconia, Nastaran Mansour, Kamjou Mansour, E. W. Van Stryland, M. J. Soileau

Faculty Bibliography 1990s

We have recently reported the formation of color centers in stabilized cubic zirconia (ZrO2, 18% Y2O3) by two‐photon absorption at 532 nm. Here we present the results of measurements of the transmission of the colored samples as a function of time at room temperature. The results are found to be in good agreement with theory that assumes the color centers diffuse out of the irradiated region. The initial distribution of centers is assumed to have a Gaussian profile. For this model, the diffusion equation was solved exactly and the diffusion constant obtained (∼3.4×10−8 cm2/s).

Multiconfiguration Hartree-Fock Calculation Of The Photoionization Of The Cs 7d Excited-State, H. P. Saha Jan 1990

Multiconfiguration Hartree-Fock Calculation Of The Photoionization Of The Cs 7d Excited-State, H. P. Saha

Faculty Bibliography 1990s

The numerical multiconfiguration Hartree-Fock method is used to calculate the photoionization cross section for the Cs 7d excited state. The electron correlation and the dynamical core-polarization effects, which are very important for photoionization-cross-section calculations of the cesium atom, have been taken into account in an ab initio manner through the configuration-interaction procedure. A minimum has been found in the total photoionization cross section. The calculation of the photoionization angular-distribution asymmetry parameter is proved to be an excellent test to determine the existence and location of the minimum in the cross section. The length and velocity forms of the cross …

Near-Threshold K-Shell Photoionization Of Argon, H. P. Saha Jan 1990

Near-Threshold K-Shell Photoionization Of Argon, H. P. Saha

Faculty Bibliography 1990s

The K-shell photoionization cross section of argon near the threshold has been obtained with the multiconfiguration Hartree-Fock method for continuum wave functions. The electron correlation and the core-relaxation effects that are very important in this process have been taken into account in the calculation very accurately in the ab initio manner through the configuration-interaction procedure. The present results are compared with the experimental measurements and are found to be in excellent agreement. The two-electron resonances that have been observed immediately above the ionization threshold have been identified and assignments have been made to these based on accurate calculations.
