1. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications
Master-uppsats, KTH/Tillämpad fysikSammanfattning : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. LÄS MER
2. Experimental studies of radiation damage in uranium nitride
Master-uppsats, KTH/FysikSammanfattning : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. LÄS MER
3. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead
Master-uppsats, KTH/FysikSammanfattning : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. LÄS MER
4. Radiation effects on wide bandgap semiconductor devices
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Gallium nitride (GaN) based high-electron-mobility transistors (HEMTs) are used in a wide variety of areas, such as 5G, automotive, aeronautics/astronautics and sensing elds ranging from chemical, mechanical, biological to optical applications. Owing superior material properties, the GaN based HEMTs are especially useful in harsh operation environments e. LÄS MER
5. Proton Arc Therapy Optimization
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : Cancer is ranked among the leading causes of death in the world. During the last decades, the development of advanced cancer treatment software has had an increasingly important role in its treatment. To treat cancer, there are many different therapies, one of which is radiation therapy. LÄS MER
