6. Charge Transport in Single-crystalline CVD Diamond
Sammanfattning : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties, as compared to other (wide bandgap) semiconductors, make it desirable to develop single-crystalline epitaxial diamond films for electronic device and detector applications.

7. Fluorine-Free Ionic Liquids and Electrolytes : From Synthesis to Energy Storage Applications
Sammanfattning : Since their introduction by Sony in 1990, lithium-ion batteries (LIBs) have acquired a sizable market share. They have the best energy densities, a high open circuit voltage, a low self-discharge rate, no memory effect, and a slow loss of charge when not in use. LÄS MER
8. Electrical properties of thermal oxides on SiC manufactured in an alumina furnace
Sammanfattning : A process to achieve high inversion channel mobility in 4H-SiC MOSFETs is needed to enable manufacturing of devices for high power applications. In this thesis, investigations on the electrical properties of oxides produced in an alumina furnace are presented. LÄS MER
9. Valley-Polarized Charge Transport in Diamond
Sammanfattning : Diamond is a wide bandgap semiconductor with extreme properties such as high thermal conductivity, high breakdown field and high carrier mobilities. These properties together with the possibility to synthesize high purity Single-Crystalline (SC) diamond by Chemical Vapor Deposition (CVD), makes it a really interesting material for electronic devices.

10. Low Frequency Impact Sound in Timber Buildings : Transmission Measurements and Simulations
Sammanfattning : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. LÄS MER
