    • Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

  • The effect of Zn1-xMgxO buffer layer deposition temperature on Cu(In,Ga)Se2 solar cells : A study of the buffer/absorber interface
  • 2009
  • Ingår i: Progress in Photovoltaics. - : Wiley. - 1062-7995 .- 1099-159X. ; 17:2, s. 115-125

    • The effect of atomic layer deposition temperature of Zn1-xMgxO buffer   layers for Cu(In,Ga)Se-2 (CIGS) based solar cell devices is evaluated.   The Zn1-xMgxO films are grown using diethyl zinc, bis-cyclopentadienyl   magnesium and water as precursors in a temperature range of 105 to 180   C High efficiency devices are produced in the region front 105 up to   135 degrees C. At a Zn1-xMgxO deposition temperature of 120 C, a   maximum cell efficiency of 15.5% is reached by using a Zn1-xMgxO layer   with an x-value of 0.2 and a thickness of 140 inn. A significant drop   in cell efficiency due to large losses in open circuit voltage and fill   factor is observed for devices grown at temperatures above 150 C. No   differences in chemical composition, structure and morphology of the   samples are observed, except for the samples prepared at 105 and 120 C   that show elemental selenium present at the buffer/absorber interface.   The selenium at the interface does not lead to major degradation of   the,solar cell device efficiency. Instead, a decrease in Zn1-xMgxO   resistivity by more than one order of magnitude at growth temperatures   above 150 C may explain the degradation in solar cell performance. From   energy filtered transmission electron microscopy, the width of the   CIGS/Zn1-xMgxO chemical interface is found to be thinner than 10 not   without any areas of depletion for Cu, Se, Zn and O.
