Publication number: 20130306927Abstract: A method of forming a metal chalcogenide material. The method comprises introducing a metal precursor and a chalcogenide precursor into a chamber, and reacting the metal precursor and the chalcogenide precursor to form a metal chalcogenide material on a substrate. The metal precursor is a carboxylate of an alkali metal, an alkaline earth metal, a transition metal, a post-transition metal, or a metalloid. The chalcogenide precursor is a hydride, alkyl, or aryl precursor of sulfur, selenium, or tellurium or a silylhydride, silylalkyl, or silylaryl precursor of sulfur, selenium, or tellurium. Methods of forming a memory cell including the metal chalcogenide material are also disclosed, as are memory cells including the metal chalcogenide material.Type: ApplicationFiled: May 21, 2012Publication date: November 21, 2013Applicant: MICRON TECHNOLOGY, INC.Inventors: Eugene P.

Publication number: 20130272944Abstract: A method for recycling organic waste material containing phosphorus oxides and metal oxides is particularly suited for recycling sewage sludge. The waste materials are mixed with chlorine carriers and then heat-treated at an air ratio of 0.85???1.6 and at least partially oxidized. The metal chlorides thus formed are drawn off and recovered and the fraction remaining after the metal chlorides have been drawn off is subjected to reduction in order to obtain elemental phosphorus.Type: ApplicationFiled: October 18, 2011Publication date: October 17, 2013Applicant: SGL Carbon SEInventor: Alfred Edlinger
