11. Chemical vapour deposition of boron and boron carbides : aspects of kinetics, mechanisms and selective deposition
Sammanfattning : .... LÄS MER
12. A Study of Group 13-Nitride Atomic Layer Deposition : Computational Chemistry Modelling of Atomistic Deposition Processes
Sammanfattning : The crystalline solids aluminium nitride (AlN), gallium nitride (GaN) and indium nitride (InN), together with their alloys, are of huge interest in the semiconductor industry. Their bandgaps span an extensive range from 6.0 eV for AlN to 0.7 eV for InN, with GaN in between at a bandgap of 3. LÄS MER
13. An Insight into the Critical Role of Microstructure and Surface Preparation on Localized Conversion Coating Deposition on Cast Al Alloys
Sammanfattning : The spontaneous cerium conversion coating formation over aluminium alloys is affected by the chemical process conditions, the surface preparation prior to conversion treatment and the microstructure of the underlying alloy. Most research performed until now focus only on the former whereas the influence of the latter two is poorly understood. LÄS MER
14. Cathodic arc deposition process
Sammanfattning : This thesis aims to expand the knowledge of fundamental mechanisms that govern the cathodic arc process. The first part of this thesis explores and explains the correlations between a rather unexplored process parameter (i.e. cathode microstructure) and the microstructure of the coatings. LÄS MER
15. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration
Sammanfattning : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.
