6. Carbide and MAX-Phase Engineering by Thin Film Synthesis
Sammanfattning : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. LÄS MER
7. Synthesis and Characterization of Multifunctional Carbide- and Boride-based Thin Films
Sammanfattning : This thesis present research on synthesis, microstructure, and properties of carbide- and boride- based thin films. The films have been synthesized by dc magnetron sputtering, and their microstructures have been characterized mainly by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, and transmission electron microscopy.

8. Aspects of Structural Evolution in Cemented Carbide – Carbide Size, Shape and Stability
Sammanfattning : Cemented carbide is a composite material used in applications like cutting tools and rock drilling inserts. The material commonly consists of WC grains embedded in a Co-rich binder phase and the material properties strongly depend on the WC grain size. LÄS MER
9. Termination and passivation of Silicon Carbide Devices
Sammanfattning : Silicon carbide rectifiers are commercially available since 2001, and MESFET switches are expected to enter the market within a year. Moreover, three inch SiC wafers can be purchased nowadays without critical defects for the device performance and four inch substrate wafers are announced for the year 2005. LÄS MER
