    Author : Amina Mirsakiyeva; Anna Delin; Igor Zozoulenko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; density functional theory; DFT; Car-Parrinello molecular dynamics; CPMD; tigh-binding; poly 3; 4-ethylenedioxythiophene ; PEDOT; selenium; PEDOS; tellurium; PEDOTe; poly p-phenylene ; poly para-phenylene ; poly 1; 4-phenylene ; naphthobischalcogenadiazoles; Fysik; Physics;

    Abstract :     Conductive polymers are also known as "organic metals" due to their semiconducting properties. They are found in a wide range of applications in the field of organic electronics. However, the growing number of experimental works is not widely supported with theoretical calculations. READ MORE

  4. 2. Polymer Light Emitting Devices : A study on how the electrode-polymer interface affects the performance of polymer light emitting devices

    Author : Per Bröms; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The research reported in this thesis is concerned with a new type of semiconductor device that can be realised by using thin films of semiconducting polymers, or conjugated polymers. In this thesis only one family of these conjugated polymers is studied, namely poly-(para-phenylene vinylene) and derivatives thereof. READ MORE

  5. 3. Electron-lattice dynamics in π-conjugated systems

    Author : Magnus Hultell (Andersson); Sven Stafström; Alessandro Troisi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charge transport; electron-lattice dynamics; polaron; adiabatic transport; electron localization; internal conversion; Computational physics; Beräkningsfysik;

    Abstract : The work presented in this thesis concerns the dynamics in π-conjugated hydrocarbon systems. Due to the molecular bonding structure of these systems there exists a coupling between the electronic system and the phonons of the lattice. READ MORE
