  4. 12. Determination of the Polaron Density in Chemically Doped Conjugated Polymers

    Author : Emmy Järsvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic semiconductors; chemical doping; spectroscopy; molecular dopants polaron density; conjugated polymers; double doping;

    Abstract : Semiconductors have become indispensable in modern electronics, playing vital roles across diverse devices such as computers, mobile phones, and solar cells. While inorganic semiconductors, such as silicon, currently dominates the industry, organic semiconductors offer promising alternatives. READ MORE

  5. 13. Growth Hormone in Athletes

    Author : Christer Ehrnborg; Göteborgs universitet; []
    Keywords : Growth hormone; IGF-I; bone markers; doping; athletes; maximum exercise test; variability; supraphysiological; body composition; physical performance; IGFBP-4; IGFBP-5;

    Abstract : Doping with growth hormone (GH) is a well-known problem both among elite athletes and among people training at gyms. It is mainly the anabolic and, to some extent, lipolytic effect of GH that is valued by its users. READ MORE

  7. 15. III-V Nanowire Solar Cells: Growth and Characterization

    Author : Gaute Otnes; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Solar cell; Photovoltaic; Metal organic vapor phase epitaxy; Nanoimprint lithography; Electron beam induced current; Current-voltage characteristics; Doping; Fysicumarkivet A:2018:Otnes;

    Abstract : To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. READ MORE
