    摘要: A method for making a free-standing, single crystal, aluminum gallium nitride (AlGaN) wafer includes forming a single crystal AlGaN layer directly on a single crystal LiAlO2 substrate using an aluminum halide reactant gas, a gallium halide reactant gas, and removing the single crystal LiAlO2 substrate from the single crystal AlGaN layer to make the free-standing, single crystal AlGaN wafer. Forming the single crystal AlGaN layer may comprise depositing AlGaN by vapor phase epitaxy (VPE) using aluminum and gallium halide reactant gases and a nitrogen-containing reactant gas. The growth of the AlGaN layer using VPE provides commercially acceptable rapid growth rates. In addition, the AlGaN layer can be devoid of carbon throughout. Because the AlGaN layer produced is high quality single crystal, it may have a defect density of less than about 107 cm−2.

    摘要: A system and process for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with ballast water. The total organic carbon content of the ballast water is ascertained and the amount of hypochlorite generated is modulated in response to the total organic carbon content of the ballast water. In one embodiment the system comprises a total organic carbon analyzer for measuring total organic carbon content.In one embodiment of the process of the invention, hypochlorite production is modulated so that the residual halogen-containing oxidizing agent is maintained in the ballast water. In another embodiment of the process, hypochlorite production is modulated to maintain a weight ratio of hypochlorite to total organic carbon in the ballast water ranging from about 1.0 to about 3.0.
