  1. 21. 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. 22. Robust TCO’s for CIGS solar cells based on indium tin oxide

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Julia Nilsson; [2022]
    Keywords : photovoltaics; solar cells; thin film photovoltaics; PV; TCO; transparent conductive oxide; indium tin oxide; ITO; CIGS; solar power; sputtering; RF sputtering; radio frequency sputtering;

    Abstract : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

  4. 23. Preparation and Characterization of Tb-Co Magnetic Films

    University essay from Uppsala universitet/Materialfysik

    Author : Roméo Beignon; [2022]
    Keywords : Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

    Abstract : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. READ MORE

  5. 24. Carbon footprint optimization for a large-scale PV on-grid System in Borlänge, Sweden

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Florian Brüstle; [2022]
    Keywords : ;

    Abstract : The aim of this master thesis is to design and analyze a photovoltaic (PV) system with the smallest possible carbon footprint. The system will be located in Borlänge, Sweden near the airport. The main components the analysis will focus on are the modules, inverters as well as the cabling. READ MORE

  6. 25. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

    University essay from Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

    Author : Björn Landeke-Wilsmark; [2022]
    Keywords : Physics and Astronomy;

    Abstract : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.
