  2. 1. Structure-dependent charge transfer at the interafce between organic thin films, and metals and metal oxides

    Author : Sareh Ahmadi; Oscar Tjernberg; Guy Le Lay; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photoelectric spectroscopy; X-ray absorption spectroscopy; organic semiconductors; phthalocyanine; charge transfer; electronic structure; dye sensitization;

    Abstract : The purpose of the research work, presented in this thesis is to offer a detailed atomic level study of interfaces created by adsorption of organic molecules on metals and metal oxides to point out significant impact of substrate, dye structure as well as different mediators on the charge transfer at these interfaces, which is proven to influence the device performance to a great extent.Adsorption of organic photosensitive molecules on metals and metal-oxides is the main focus of this thesis.

  4. 2. Light polarization in single molecule spectroscopy: From visualization of structural anisotropy and energy transfer to super-resolution imaging with orientational contrast

    Author : Daniel Thomsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Single-molecule spectroscopy; π-conjugated polymers; blinking; fluorescence brightness; low temperature; polarization anisotropy; 2D polarization; energy transfer; super resolution; Fourier transform;

    Abstract : Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. READ MORE
