    摘要: Methods and systems for removing impurities from an electrolytic salt are disclosed. After removal of impurities from the salt, the salt can be subjected to electrorefining to produce high-purity materials, for example silicon. Impurities are removed from the salt using a system that includes a first working electrode, a counter electrode, and at least one reference electrode. A second working electrode can also be utilized. The salt may be utilized in an electrorefining system, for example a system operated in a single phase or multiple phase operation to produce high-purity materials, such as solar-grade silicon.

    摘要: The present invention relates generally to compositions, kits and methods of providing improved semiconductor surfaces free of dangling bonds and free of strained bonds. One method provides for preventing interfacial reactions between a semiconductor surface and metal or dielectric comprising the steps of preparing a passivated semiconductor surface using a valence-mending agent and depositing a layer of metal or dielectric on the valence-mended semiconductor surface. As further described, a semiconductor surface free of interfacial reactions between the surface and a second molecular species may include a semiconductor surface with one atomic layer of valence-mending atoms, wherein valence mending occurs after introducing the semiconductor surface to a passivating agent. The present invention also includes a kit for preventing interfacial reactions from occurring on a semiconductor surface comprising a passivating agent and an instructional manual.
