The conductive paste composition includes metal powder coated with an organosilica compound formed by polymerization of an organosilane compound having a structure of RnSi(OR?)4-n (wherein R is selected from alkyl and aryl groups, each having 20 or less carbon atoms, R? is any one of the alkyl groups having 4 or less carbon atoms, and n is 1 or 2). Since the organosilica coating layer is coated around the metal powder particles, preventing the metal powder particles from being agglomerated, thereby allowing the conductive paste composition having very superior dispersibility to be manufactured. In addition, effects such as inhibited oxidation of the metal powder during plasticization and effectively inhibited shrinkage of the metal powder during sintering may be accomplished.Type: ApplicationFiled: December 14, 2011Publication date: June 21, 2012Inventors: Jai Joon LEE, Hyun Chul Jung, Jae Man Park, Jong Han Kim

Publication number: 20120138870Abstract: The present invention teaches an effective mechanism for enhancing thermoelectric performance through additional conductive bands. Using heavily doped p-PbTe materials as an example, a quantitative explanation is disclosed, as to why and how these additional bands affect the figure of merit. A high zT of approaching 2 at high temperatures makes these simple, likely more stable (than nanostructured materials) and Tl-free materials excellent for thermoelectric applications.Type: ApplicationFiled: November 2, 2011Publication date: June 7, 2012Applicant: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: G.
