We report the results of an extensive study employing numerous methods to characterize carrier transport within copper indium gallium sulfoselenide (CIGSS) photovoltaic devices, whose absorber layers were fabricated by diverse process methods in mult

The elastic interaction energy between tetragonal zirconia precipitates for different mutual orientations is considered. The results of numerical analysis of this procedure are compared with experimentally observed preferred orientation relationships

A method for the correction of the size of spherical, disc-like or ellipsoidal particles in foils of finite thickness has been derived. This method corrects for errors due to spheres (or ellipsoids or discs) centred outside the foil that are observed

Using a grazing emission method, we have made measurements of 22.6-GeV electron impact ionization cross sections at the front and back faces of ∼ 70-µm thick Al and Cu foils. These give, respectively, the cross sections without and with a density

The internal and transmitted fields, calculated for a collimated gaussian beam incident on a narrow-band-pass filter at angle, predict a lateral beam shift. For a focused incident beam, the transmitted beam is distorted.

Random roughness of an optical surface reduces its specular reflectance and transmittance by the scattering of light. The reduction in reflectance can be modeled by a homogeneous layer on the surface if the refractive index of the layer is intermedia

Thin films of CdTel-xSx with bulk atomic compositions, x≡[S]/([S]+[Te]), ranging from 0 to 0.45 were deposited by vacuum co-evaporation of CdTe and CdS with substrate temperatures of 200 and 250°C. X-ray diffraction analysis revealed that films wi

We have made an absolute measurement of the Cu {ital K}-shell impact ionization cross section by 5.1-GeV electrons, which demonstrates directly a density effect predicted by Fermi in 1940. By determining the ratio of the {ital K} x-ray yield from a t
