    Sammanfattning : 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. LÄS MER

  5. 4. Electrochemical Deposition of Nanostructured Metal/Metal-Oxide Coatings

    Författare :Jonas Eskhult; Leif Nyholm; Jan-Otto Carlsson; Jay Switzer; Uppsala universitet; []
    Nyckelord :Inorganic chemistry; electrochemical deposition; local pH; Cu2O; Sb2O3; complex; EQCM; reduction; Oorganisk kemi;

    Sammanfattning : Electrochemical deposition finds applications in the electronics- and protective coating industries. The technique is a versatile tool for the synthesis of alloys and thin films. Knowledge of the fundamental aspects of the electrode processes enables the design of nanostructured materials. LÄS MER

  7. 5. Chemical Vapour Deposition of Undoped and Oxygen Doped Copper (I) Nitride

    Författare :Anna Fallberg; Jan-Otto Carlsson; Mikael Ottosson; Kwang-Leong Choy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical vapour deposition; copper hexafluoroacetylacetonate; copper I nitride; copper I oxide; multilayers; oxygen doping; Organic chemistry; Organisk kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : In science and technology there is a steadily increased demand of new materials and new materials production processes since they create new application areas as well as improved production technology and economy. This thesis includes development and studies of a chemical vapour deposition (CVD) process for growth of thin films of the metastable material copper nitride, Cu3N, which is a semiconductor and decomposes at around 300 oC.
