1. Electrical Characterization of Silicon Nanogaps
Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER
2. Experimentally Based HFET Modeling for Microwave and Millimeter Wave Applications
Sammanfattning : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. LÄS MER
3. Integrated Oscillators in InGaP/GaAs HBT Technology
Sammanfattning : The thesis presents two major concerns in the design of low phase-noise MMIC VCOs; the active device model and the simulation tool. Besides, several design techniques to improve VCO tuning range and phase noise are investigated. The VCOs designed in this work are implemented in InGaP/GaAs HBT technology. LÄS MER
4. Spontaneous and stimulated X-ray Raman scattering
Sammanfattning : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. LÄS MER
5. Effect of surface characteristics on cellular adherence and activity
Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER
