  1. 1. Sublimation temperature prediction of OLED materials : using machine learning

    University essay from Uppsala universitet/Analys och partiella differentialekvationer

    Author : Niklas Norinder; [2023]
    Keywords : Semiconductors; OLED; machine learning; vapor deposition; sublimation; molecular property prediction; regression; ensemble learning; deep learning;

    Abstract : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. READ MORE

  3. 2. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Thomas Moberg; [2018]
    Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE

  4. 3. Surface energy modification of metal oxide to enhance electron injection in light-emitting devices : charge balance in hybrid OLEDs and OLETs

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Sergio Apicella Fernandez; [2017]
    Keywords : organic; inorganic; semiconductors; OLEDs; OLETs; TFT; stack; thin-film; deposition; spin-coating; thermal; evaporation; process; reactive; sputtering; luminescence; EQE; PEIE; metal-oxide; ZnO; ZnO:N; MoO3; F8BT; Alq3; NPB;

    Abstract : Organic semiconductors (OSCs) present an electron mobility lower by several orders of magnitude than the hole mobility, giving rise to an electron-hole charge imbalance in organic devices such as organic light-emitting diodes (OLEDs) and organic light-emitting transistors (OLETs). In this thesis project, I tried to achieve an efficient electron transport and injection properties in opto-electronic devices, using inorganic n-type metal oxides (MOs) instead of organic n-type materials and a polyethyleneimine ethoxylated (PEIE) thin layer as electron transport (ETLs) and injection layers (EILs), respectively.

  5. 4. Synthesis and Reactivity of N-heterocyclic Gold (I) Complexes

    University essay from Lunds universitet/Kemiska institutionen

    Author : Lars Erik Andreas Ehnbom; [2013]
    Keywords : Oorganisk kemi; inorganic chemistry; Chemistry;

    Abstract : Populärvetenskaplig sammanfattning Metallorganisk kemi är en gren av kemin som fokuserar på att utveckla nya reaktioner med hjälp av övergångsmetaller som t.ex. järn, kobolt och guld. Genom att använda övergångsmetaller i kemi är det möjligt att bilda nya reaktioner som man med konventionell organisk kemi inte kan få tillgång till. READ MORE

  6. 5. Dyeing of Wool and Silk Fibres with a Conductive Polyelectrolyte and Comparing Their Conductance

    University essay from Högskolan i Borås/Institutionen Textilhögskolan

    Author : Muhammad Ahsen Khan; [2012]
    Keywords : conjugated polyelectrolyte; conductive polymers; conductive protein fibres; fluorescent dyes;

    Abstract : Polyelectrolytes are conductive polymers because of their ionic side group and PEDOT-S is one of those conductive polyelectrolytes. Previously, recombinant silk fibre has been dyed with PEDOT-S. PEDOT-S showed that it can be dyed with recombinant silk fibre over a very wide range of pH from 11 to 1.7. READ MORE
