  1. 21. Theoretical Investigations of Boron Related Materials Using DFT

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Igor Arvidsson; Uppsala universitet.; [2007]
    Keywords : Inorganic chemistry; boron nitride; density functional theory; chemical vapour deposition; atomic layer deposition; surface reactivity; adsorption; abstraction; computational chemistry; Oorganisk kemi;

    Abstract : In the history of Chemistry, materials chemists have developed their ideas mainly by doing experiments in laboratories. The underlying motivation for this laboratory work has generally been pure curiosity or the ambition to find a solution to a specific problem. READ MORE

  2. 22. Deposition of Al-doped ZnO films by high power impulse magnetron sputtering

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Martin Mickan; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Transparent conducting oxides (TCOs) are an important class of materials with many applications such as low emissivity coatings, or transparent electrodes for photovoltaics and flat panel displays. Among the possible TCO materials, Al-doped ZnO (AZO) is studied due to its relatively low cost and abundance of the raw materials. READ MORE

  3. 23. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols

    University dissertation from Stockholm : Institutionen för analytisk kemi

    Abstract : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. READ MORE

  5. 25. Carbon Nanotube Transistors: Nanotube Growth, Contact Properties and Novel Devices

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johannes Svensson; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotube; chemical vapour deposition; Field effect transistor; Marangoni convection; Schottky barrier;

    Abstract : Carbon nanotubes (CNTs) are envisioned to be used as the basic building blocks in future electronics due to their excellent electronic properties such as high mobility, compatibility with high-k dielectrics and small diameters resulting in advantageous electrostatics. This thesis is divided into three separate topics related to increasing the fabrication yield and performance of CNT field effect transistors (CNTFETs). READ MORE
