    Abstract : This thesis concerns the study of D–π–A type dyes as sensitizers for NiO-based p-type dye-sensitized solar cells. The focus has been on the design and synthesis of efficient dyes and the identification of parameters limiting the solar cell performance. READ MORE

  5. 5. Semiconductor Nanowires: Epitaxy and Applications

    Author : Thomas Mårtensson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; semiconductor; nanotechnology; nanowires; crystal growth; metal-organic vapour phase epitaxy; III-V; silicon; MOVPE; light-emitting diode; single-electron transistor; cell;

    Abstract : Semiconductor nanowires are nanoscale objects formed by bottom-up synthesis. In recent years their unique properties have been exploited in fields such as electronics, photonics, sensors and the life sciences. In this work, the epitaxial growth of nanowires and their applications were studied. READ MORE
