    Notes: Theoretical results recently obtained for polarizability of intersecting spherical particles have been compared with those for polarizability of intersecting cardioidal particles resembling the spherical shape. Calculations based on a modified Parseval Rule have been performed for a number of metals in a dielectric matrix in a quasistatic approximation. A large difference in the polarizabilities has been found in spite of a striking similarity in their shapes. An unexpected small value for both the real and the imaginary part of the polarizability of cardioidal shaped metal particles occurs at wavelengths where simple metal spheres absorb strongly. A Maxwell-Garnett model has been used to compare the optical properties of composite materials containing the cardioidal and intersecting spherical particles of interest. It has been found that a composite containing cardioid shaped particles in a dielectric matrix can have an unusual response. Its absorption is very close to zero, while the refractive index is close to that of the fully dense host. © 1996 American Institute of Physics.

    Notes: The polarization of a pair of merging spheres and merging cylinders of any complex dielectric constant immersed in an external electric field has been solved. Any degree of intersection, including touching, is covered by the result. The method for cylinders is based on the solution of Laplace's equation with boundary conditions on the conjugate surfaces in a modified bicylindrical frame. The result is presented as an integral over a continuum of eigenstates. For merging spherical particles solving the boundary problem requires a Miller–Fok integral transformation. Imaginary parts of polarizabilities were calculated for aluminum cylinders and spheres to assess the spectral absorption response of small merging particles. The relative spacing has a significant influence on optical response.

    Notes: We describe a simple and inexpensive potentiostat, incorporating current boosting and filtering circuitry for use in the study of coloration and bleaching in electrochromic thin films. The system is sufficiently flexible to permit utilization in other electrochemical applications.

    Notes: The optical properties (n,k,ε,neff) of chemically ordered a-Si1−xCx@B:H alloys have been measured and then analyzed with the effective-medium theory. Included is the first experimental result for an amorphous binary semiconductor that is known to be almost fully chemically ordered, and represented by the formula a-SiC0.64@B:H. Chemical order is induced by heavy dilution of the plasma with hydrogen. Chemical ordering shifts absorption to shorter wavelengths. Analysis using a scaling theory to define optical constants of different tetrahedron components leads to serious errors in the a-Si1−xCx@B:H series.

    Notes: The variations in conductivity, under illumination of amorphous semiconductors, is examined as a function of the dark Fermi level (EF) using a simple, generally accurate approach which eliminates the need for a complete numerical solution of equations covering generation, recombination, and trapping. The enhanced photoconduction on doping is readily quantified along with the reduced photosensitivity (total to dark conductivity ratio). Various models can be more readily assessed. Predictions are examined in detail for the often used exponential gap state model. The associated Rose model result for the intensity dependence is seen to be an asymptotic limit which becomes less applicable as dark conductivity increases. Temperature dependence is also examined. Emphasis is on doping, but contrasts are also drawn between the effects of a homogeneous and inhomogeneous shift in dark activation energy. The reduction in the exponent γ for the intensity dependence is far more pronounced when external fields modify the dark conductivity.

    Notes: Very thin gold films were prepared on glass by ion plating (IP) and by conventional evaporation (CE). Below a certain thickness—∼9 nm for IP and ∼15 nm for CE—the films comprised a metal network; above this thickness we found uniform films. Optical properties were recorded by spectrophotometry. Conspicuous near-infrared transmittance plateaus were seen in network films. This effect is conducive to high solar transmission. The spectral features were explained from effective medium theories based on the film structure. The uniform films were consistent with the Drude theory, provided that an anomalously large frequency dependence of the relaxation energy was invoked. Significant induced transmission was found in calculations on dielectric/gold/dielectric coatings. Our results lead to improved noble-metal-based transparent infrared reflectors for potential use on energy efficient windows.
