With the overall critical current density,J c , remaining low for PbMo6S8, the addition of 0.3 at. % Sn noticcably improved the performance. The enhancement occurs despite the presence of excess Pb and a slightly suppressedT c . The increase inJ c ca

The change in the surface and bulk compositions of high-T c Bi-Pb-Sr-Ca-Cu-O and Y-Ba-Cu-O system superconductors caused by electron beam irradiation at room temperature have been investigated using high-resolution Auger electron spectroscopy (AES).

High temperature superconducting ceramics, based on YBa 2 Cu 3 O 7 , were prepared from oxides and carbonates, from the pre-reacted binary compounds BaCuO 2 and Cu 2 Y 2 O 5 , or by partial substitution of Y 2 O 3 and BaO by Bi 2 O 3 and PbO, respect

Diamond thin films were grown by microwave plasma and hot filament chemical vapor deposition (MPCVD and HFCVD, respectively) techniques. Films were systematically characterized by x-ray diffraction, micro-Raman spectroscopy, scanning electron microsc

High resolution Auger electron spectroscopy was performed on (111) and (100) facets as well as on a microvoid of polycrystalline diamond films. Auger fine structure analyses of these facets indicate anomalous line shapes when electron beam was focuse

A large increase (similar to 8 X) in critical current density, J(c), was achieved for in situ laser ablated YBa2Cu3O7-delta-Ag films. High-resolution Auger electron spectroscopic investigation indicates that the Ag-doped films are stoichiometric with
