1. Alumina Thin Films : From Computer Calculations to Cutting Tools
Sammanfattning : The work presented in this thesis deals with experimental and theoretical studies related to alumina thin films. Alumina, Al2O3, is a polymorphic material utilized in a variety of applications, e.g., in the form of thin films. LÄS MER
2. ZrB2 Thin Films : Growth and Characterization
Sammanfattning : Zirconium diboride, ZrB2, is a ceramic material with bulk properties such as high melting point (3245 °C), high hardness (23 GPa), and low resistivity (~8 μΩcm). Thin film growth of ZrB2 using physical vapor deposition has suffered from problems with films deviating from stoichiometry and with high levels of contaminants, especially high oxygen content.

3. Nanostructured carbon-based thin films : prediction and design
Sammanfattning : Carbon-based thin films are a vast group of materials of great technological importance. Thanks to the different bonding options for carbon, a large variety of structures (from amorphous to nanostructured) can be achieved in the process of film synthesis. LÄS MER
4. Nanocrystalline Tungsten Trioxide Thin Films : Structural, Optical and Electronic Characterization
Sammanfattning : This thesis concerns experimental studies of nanocrystalline tungsten trioxide thin films. Functional properties of WO3 have interesting applications in research areas connected to energy efficiency and green nanotechnology. LÄS MER
5. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C
Sammanfattning : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. LÄS MER
