1. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies
Sammanfattning : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. LÄS MER
2. Production and Characterization of ZrN and PuN Materials for Nuclear Fuel Applications
Sammanfattning : At the heart of a nuclear reactor resides its fuel. The chemical composition of the nuclear fuel affects the performance of several key properties important for the overall operation and safety performance of the reactor. LÄS MER
3. Metal Gate Technology for Advanced CMOS Devices
Sammanfattning : The development and implementation of a metal gate technology (alloy, compound, or silicide) into metal-oxide-semiconductor field effect transistors (MOSFETs) is necessary to extend the life of planar CMOS devices and enable further downscaling. This thesis examines possible metal gate materials for improving the performance of the gate stack and discusses process integration as well as improved electrical and physical measurement methodologies, tested on capacitor structures and transistors.

4. Preparation and Characterisation of Sputtered Titanium- and Zirconium Nitride Optical Films
Sammanfattning : Multilayered interference coatings based on titanium- and zirconium nitride and designed for solar control have been prepared using reactive d c magnetron sputtering. Preparation effects and degradation mechanisms were investigated. It was shown that the quality of the nitride strongly depends on the degree of crystallinity in the underlying oxide. LÄS MER
5. Nitride Thin Films for Thermoelectric Applications : Synthesis, Characterization and Theoretical Predictions
Sammanfattning : Thermoelectrics is the reversible process which transforms a temperature gradient across a material into an external voltage through a phenomenon known as the Seebeck effect. This has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.
