11. Properties and applications of materials based on graphite oxide
Sammanfattning : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. LÄS MER
12. CVD and ALD of Group IV- and V-Oxides for Dielectric Applications
Sammanfattning : Due to the constantly decreasing dimensions of electronic devices, the conventional dielectric material in transistors and capacitors, SiO2, has to be replaced by a material with higher dielectric constant. Some of the most promising candidates are tantalum oxide,Ta2O5, zirconium oxide, ZrO2 and hafnium oxide, HfO2. LÄS MER
13. Atomic Layer Deposition of Copper, Copper(I) Oxide and Copper(I) Nitride on Oxide Substrates
Sammanfattning : Thin films play an important role in science and technology today. By combining different materials, properties for specific applications can be optimised. LÄS MER
14. Employing Metal Iodides and Oxygen in ALD and CVD of Functional Metal Oxides
Sammanfattning : 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. LÄS MER
15. Selection of oxygen carriers for chemical-looping combustion using methane as a fuel
Sammanfattning : In order to meet new demands on clean energy producing technologies, chemical-looping combustion could play an important role. With this technique, CO2 from the flue gases can be separated and collected without excessive energy and efficiency penalty. This is because nitrogen from the combustion air is never mixed with the fuel. LÄS MER
