    • Band alignment of SnS/Zn(O,S) heterojunctions in SnS thin film solar cells 

      Sun, Leizhi; Haight, Richard; Sinsermsuksakul, Prasert; Bok Kim, Sang; Park, Helen Hejin; Gordon, Roy Gerald (American Institute of Physics, 2013)
      Band alignment is critical to the performance of heterojunction thin film solar cells. In this letter, we report band alignment studies of SnS/Zn(O,S) heterojunctions with various compositions of Zn(O,S). Valence band ...
    • Enhancing the Efficiency of SnS Solar Cells bia Band-Offset Engineering with a Zinc Oxysulfide Buffer Layer 

      Sinsermsuksakul, Prasert; Hartman, Katy; Kim, Sang Bok; Sun, Leizhi; Park, Helen Hejin; Chakraborty, Rupak; Buonassisi, Tonio; Gordon, Roy Gerald (American Institute of Physics, 2013)
      SnS is a promising earth-abundant material for photovoltaic applications. Heterojuction solar cells were made by vapor deposition of p-type tin(II) sulfide, SnS, and n-type zinc oxysulfide, Zn(O,S), using a device structure ...
    • High Electrical Conductivity in Ni 3 (2,3,6,7,10,11-hexaiminotriphenylene) 2 , a Semiconducting Metal–Organic Graphene Analogue 

      Sheberla, Dennis; Sun, Lei; Blood-Forsythe, Martin; Er, Suleyman; Wade, Casey R.; Brozek, Carl K.; Aspuru-Guzik, Alan; Dincă, Mircea (American Chemical Society (ACS), 2014)
      Reaction of 2,3,6,7,10,11-hexaaminotriphenylene with Ni2+ in aqueous NH3 solution under aerobic conditions produces Ni3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a new two-dimensional metalorganic framework ...
    • Improved Thin Film Solar Cells Made by Vapor Deposition of Earth-Abundant Tin(II) Sulfide 

      Sun, Leizhi (2014-06-06)
      Tin(II) sulfide (SnS) is an earth-abundant, inexpensive, and non-toxic absorber material for thin film solar cells. SnS films are deposited by atomic layer deposition (ALD) through the reaction of a tin precursor, ...
    • \((Sn,Al)O_x\) Films Grown by Atomic Layer Deposition 

      Heo, Jae Yeong; Liu, Yiqun; Sinsermsuksakul, Prasert; Li, Zhefeng; Sun, Leizhi; Noh, Wontae; Gordon, Roy Gerald (American Chemical Society, 2011)
      \((Sn,Al)O_x\) composite films with various aluminum (Al) to tin (Sn) ratios were deposited using an atomic layer deposition technique. The chemisorption behavior of cyclic amide of tin(II) and trimethylaluminum were ...
