Group III Impurity Doped Zinc Oxide Thin Films Prepared by RF Magnetron Sputtering

Tadatsugu Minami、Hirotoshi Sato、Hidehito Nanto 等 4 位作者1985-10-01OpenAlex

The detailed study of electrical properties in group III impurity doped ZnO thin films prepared by rf magnetron sputtering is described. The resistivity is lowered by doping of B, Al, Ga and In into ZnO films. The characteristic features of ZnO films doped with group III elements except for B are their high carrier co…

Surface-mediated enhancement of optical phase conjugation in metal colloids

D. Ricard、Ph. Roussignol、Chr. Flytzanis1985-10-01OpenAlex

We show that the optical phase-conjugated reflectivity from silver and gold colloids is enhanced by several orders of magnitude. The reflectivity on resonance is comparable with that of CS(2) for metal-particle volume concentration of a few parts in 10(6). We trace this enhancement to the nonlinearities of the electro…

Dinuclear Complexes with Predictable Magnetic Properties

Olivier Kahn1985-10-01OpenAlex

Abstract When two paramagnetic transition metal ions are present in the same molecular entity, the magnetic properties can be totally different from the sum of the magnetic properties of each ion surrounded by its nearest neighbors. These new properties depend on the nature and the magnitude of the interaction between…

TREOR, a semi-exhaustive trial-and-error powder indexing program for all symmetries

P.‐E. Werner、Lars Eriksson、Marianne Westdahl1985-10-01OpenAlex

An indexing program, TREOR, mainly based on trial-and-error methods is described. The program contains separate routines for cubic, tetragonal, hexagonal, orthorhombic, monoclinic and triclinic symmetries. Ten years usage has been analysed to improve the original program. For monoclinic indexing a specific short-axis…

Dielectric properties and phase transitions in (CH3NH3)3Sb2Br9

R. Jakubas、Zbigniew Galewski、L. Sobczyk 等 4 位作者1985-09-30Journal of Physics C Solid State Physics

X-ray diffraction, dielectric and differential scanning calorimetry studies have been performed on (CH 3 NH 3 ) 3 Sb 2 Br 9 crystals. The first-order structural phase transitions at 168 and 131K have been revealed to be related most probably to a freezing of the reorientational motion of CH 3 NH 3 + cations.

Retardation effects in the interaction of charged particle beams with bounded condensed media

Rafael Garcia‐Molina、A. Gras-Martí、A. Howie 等 4 位作者1985-09-30Journal of Physics C Solid State Physics

The interaction of a relativistic electron beam, travelling parallel to the surface of a semi-infinite medium, is analysed. The specific energy loss of the beam and the probability of excitation of surface and bulk modes in the medium are calculated. Beams both external and internal with the medium are considered, and…

Generation of Surface Excitations on Dielectric Spheres by an External Electron Beam

T. L. Ferrell、P. M. Échenique1985-09-30Physical Review Letters

The energy loss and differential probability of energy losses is calculated to all multipole orders for a charged particle moved uniformly past a sphere. The sphere's response is characterized by use of a local dielectric function.

Quasicrystal with One-Dimensional Translational Symmetry and a Tenfold Rotation Axis

Leonid A. Bendersky1985-09-30Physical Review Letters

Studies of phase formation in rapidly solidified Al-Mn alloys (composition range 18-22 at.% Mn) show that an icosahedral phase is replaced by another noncrystallographic phase, a decagonal phase. The decagonal phase is another example of quasicrystal: It has a noncrystallographic point group ($\frac{10}{m}$ or $\frac{…

Fracture Mechanics of Polymers

K. Lawrence DeVries、R.J. Nuismer1985-09-25ACS symposium series

Failure in materials is a complex phenomenon that is not well understood and is currently the subject of considerable research effort. Failure analysis in polymers is particularly complex because properties are not only functions of the chemical nature of the polymer but also highly dependent on the details of its phy…

Chemistry and Technology of Acrylic Resins for Coatings

William H. Brendley、R. Bakule1985-09-25ACS symposium series

For the past 50 years, protective and decorative coatings based on acrylic and methacrylic polymers have found increasing use in a variety of industrial and trade sale applications. This expanded usage has occurred because of the versatile and unique properties of these polymers and because of the development of large…

The technology of plasticizers fostered an enormous growth in use of plastics. It provided dozens of industries with a progressively widened spectrum of useful new materials whose flexibility (and concomitant physical properties) could be tailored to a need. It preceded by many years the appearance of synthetic commer…

Transport Properties of Polymers

D.R. Paul1985-09-25ACS symposium series

The transport of small molecules, such as gases, vapors, or liquids, in polymers has been of intense interest to engineers and scientists for many years. Early studies of gas transport in elastomers were motivated by concerns about gas loss or interchange from automobile inner tubes, rubber balloons, cable insulation,…

An Introduction to Corrosion Control by Organic Coatings

Ray A. Dickie1985-09-25ACS symposium series

The term "corrosion" has been applied to a wide variety of processes that have in common a degradation of the chemical or physical state of a material upon exposure to an aggressive environment. More commonly, the term is restricted to chemical degradation of a metal by its environment. The technological and economic…

Structure-Property Relationships in Polymers

Turner Alfrey1985-09-25ACS symposium series

The common central structural feature of organic macromolecules is the chain of covalently bonded atoms. Bond lengths and bond angles are rather rigidly fixed, but restricted rotation about single bonds permits a polymer chain to assume a wide range of three-dimensional conformations. At elevated temperatures, bond ro…
