  2. 1. Employing Metal Iodides and Oxygen in ALD and CVD of Functional Metal Oxides

    Author : Jonas Sundqvist; Anders Hårsta; Roy Gordon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; CVD; ALD; tantalum oxide; hafnium oxide; tin oxide; epitaxy; Ta2O5; HfO2; SnO2; XRD; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : Many materials exhibit interesting and novel properties when prepared as thin films. Thin film metal oxides have had an impact on the technological progress of the microelectronics mainly due to their electrical and optical properties. READ MORE

  4. 2. Quantum chemical characterization of oxide nanoparticles and interactions on their surfaces

    Author : Marta Galynska; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cluster models; TiO2 nanoparticles; anatase; rutile; brookite; group-IV oxides; DFT;

    Abstract : Titanium dioxide and related oxide materials have been investigated using density functional theory calculations. Nanocrystalline particles were modelled by a finite cluster approach. READ MORE

  5. 3. Charge Separation on Localized Surface Plasmon and Hot Carrier Transfer to Semiconductors

    Author : Yocefu Hattori; Jacinto Sá; Stephan Link; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonics; hot carrier; metal nanoparticles; semiconductors; ultrafast transient absorption spectroscopy; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The relatively recent discovery that plasmonic nanoparticles generate energetic electron-hole pairs known as hot carriers has been the source of interest from many scientific groups. The capability to extract these short-lived hot carriers from metal nanoparticles (NPs) might potentially lead to applications in solar cells, photodetection, and photocatalysis. READ MORE

  6. 4. Nanostructured Metal Oxide Semiconductors for Functional Applications

    Author : Anton Landström; Isabella Concina; Alberto Vomiero; Caterina Soldano; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : This thesis is about nanostructured metal oxides, their properties, and some of their applications. Semiconducting metal oxides like TiO2, ZnO,and SnO2 have a wide band gap, which means they absorb UV light andgenerate electron-hole pairs. READ MORE

  7. 5. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments : Microstructure, corrosion initiation, patina evolution and metal release

    Author : Xian Zhang; Inger Odnevall Wallinder; Christofer Leygraf; Manuel Morcillo; KTH; []
    Keywords : atmospheric corrosion; chloride deposition; Zn-Al alloy coatings on steel microstructure; Cu sheet and Cu alloys; microstructure; corrosion initiation; corrosion product evolution; metal release; SEM; IRAS; CRM.; Kemi; Chemistry;

    Abstract : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.
