   Author : Tobias Törndahl; Jan-Otto Carlsson; Karin Larsson; Mikael Ottosson; Lauri Niinistö; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Atomic Layer Deposition; ALD; copper; copper I oxide; copper I nitride; deposition pathway; CuCl; Cu hfac 2; oxide substrates; epitaxy; DFT; ab-initio; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Abstract : Thin films play an important role in science and technology today. By combining different materials, properties for specific applications can be optimised. READ MORE

4. 2. Chemical Vapour Deposition of Undoped and Oxygen Doped Copper (I) Nitride

   Author : Anna Fallberg; Jan-Otto Carlsson; Mikael Ottosson; Kwang-Leong Choy; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

5. 3. Atomic layer epitaxy of copper

   Author : Per Mårtensson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Atomic Layer Epitaxy; ALE; copper; ab initio calculations; DFT; CuCl; Cu thd 2; selectivity; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : The high electric and thermal conductivity of copper has made it to a prime candidate as interconnect material in future integrated circuits. In this thesis, Atomic Layer Epitaxy has been used to deposit thin copper films on a variety of substrates, using both CuCl and Cu(II)2,2,6,6-tetramethyl-3,5-heptanedionate, Cu(thd)2, as precursors and hydrogen as reducing agent.

6. 4. Corrosion-induced release of zinc and copper in marine environments

   Author : Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. READ MORE

7. 5. Nanoscale studies of the atmospheric corrosion of copper protected by ultrathin organic films

   Author : Weijie Zhao; C. Magnus Johnson; Christopher Leygraf; Guido Grundmeier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; corrosion inhibition; Langmuir-Blodgett LB deposition; self-assembly deposition; nano-FTIR; octadecylphosphonic acid ODPA .; Kemi; Chemistry;

   Abstract : Copper (Cu) has been utilised by humans for millenniums and has become an indispensable metal in modern industry and in our infrastructure. However, corrosion, as a natural process for metallic materials, takes place on copper surfaces in most environments. READ MORE
