    Notes: It is shown that care must be exercised in using digital equipment when making Hall measurements in a van der Pauw setup employing the ASTM standard method. This arises because of quantization error when working near the sensitivity limit of the equipment. For materials with small Hall mobilities (〈100 cm2/V s) this can lead to an incorrect specification of the carrier type and inconsistent mobility behavior. A simple averaging and sampling procedure is suggested to suppress this type of behavior and is found to be sufficient to obtain reliable and repeatable Hall voltages and coefficients.

    The effect of substrate on the morphology of CuInSe2 films prepared by chemical spray pyrolysis for CuInSe2/CdS solar cells (1990)

    Notes: This communication provides a detailed examination of the morphology of thin films of CuInSe2 prepared by chemical spray pyrolysis on borosilicate glass, molybdenum-coated glass, and CdS substrates. The latter two are used in thin-film heterojunction solar cells of CuInSe2/CdS in the backwall and reverse backwall (RBW) configurations, respectively, and hence are of great technological interest. The pseudoepitaxial growth of CIS on CdS and its low deposition temperature (250 °C) which inhibits interdiffusion suggest that one should prepare CuInSe2/CdS solar cells in the RBW configuration.

    Factors affecting the optical properties of metal-semiconductor composites (1997)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The variation in the optical properties of metal-semiconductor composites (MSC) thin films due to particle-size distribution, metal volume fraction, film thickness, semiconductor dielectric constant, and microstructure are treated in a unified manner. These parameters are treated within the dynamic effective medium approximation which has been shown to accurately describe the optical properties of experimentally prepared MSC. The results of this treatment are successfully applied to Ag–Si composite systems. © 1997 American Institute of Physics.
