Patent number: 9852927Abstract: Two-dimensional (2D) transition-metal dichalcogenides have emerged as a promising material system for optoelectronic applications, but their primary figure-of-merit, the room-temperature photoluminescence quantum yield (QY) is extremely poor. The prototypical 2D material, MoS2 is reported to have a maximum QY of 0.6% which indicates a considerable defect density. We report on an air-stable solution-based chemical treatment by an organic superacid which uniformly enhances the photoluminescence and minority carrier lifetime of MoS2 monolayers by over two orders of magnitude. The treatment eliminates defect-mediated non-radiative recombination, thus resulting in a final QY of over 95% with a longest observed lifetime of 10.8±0.6 nanoseconds. Obtaining perfect optoelectronic monolayers opens the door for highly efficient light emitting diodes, lasers, and solar cells based on 2D materials.Type: GrantFiled: October 15, 2016Date of Patent: December 26, 2017Assignee: The Regents of the University of CaliforniaInventors: Matin Amani, Der-Hsien Lien, Daisuke Kiriya, James Bullock, Ali Javey

Patent number: 9620699Abstract: An insulating substrate is prepared. In this substrate, plural via holes penetrating in a thickness direction are filled with a conductive paste. This paste is produced by adding an organic solvent to a powder of an, and by processing the power of the alloy to a paste. The substrate is then pressed from a front surface and a back surface of the substrate, while being heated. The conductive paste is solid-phase sintered and interlayer connecting members are formed. A front surface protective member is disposed on a front surface of the substrate and a back surface protective member is disposed on a back surface of the substrate, and a laminate is formed. The laminate is integrated by a lower pressure being applied while heating at a lower temperature, compared to the temperature and pressure in the process of forming the interlayer connecting members.Type: GrantFiled: January 23, 2014Date of Patent: April 11, 2017Assignee: DENSO CORPORATIONInventors: Eijirou Miyagawa, Keita Saitou, Yoshihiko Shiraishi, Yoshitaro Yazaki, Toshihisa Taniguchi, Atusi Sakaida

Patent number: 9353445Abstract: Solid state thermoelectric energy conversion devices can provide electrical energy from heat flow, creating energy, or inversely, provide cooling through applying energy. Thick film methods are applied to fabricate thermoelectric device structures using microstructures formed through deposition and subsequent thermal processing conditions. An advantageous coincidence of material properties makes possible a wide variety of unique microstructures that are easily applied for the fabrication of device structures in general. As an example, a direct bond process is applied to fabricate thermoelectric semiconductor thick films on substrates by printing and subsequent thermal processing to form unique microstructures which can be densified. Bismuth and antimony telluride are directly bonded to flexible nickel substrates.Type: GrantFiled: January 16, 2015Date of Patent: May 31, 2016Assignee: BERKEN ENERGY LLCInventor: Ronald R. Petkie
