1. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. LÄS MER
2. Traditionell timring i lod, våg och vinkel med kroppen som instrument
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : This thesis takes a look at how traditional log houses can be built with only the use of old measurements (by using its bodily counterparts such as thumbs, forearms and feet) combined with the two senses touch (by building with an axe) and sight for maintaining the structure and its parts plumb, level and also having correct or perpendicular angles. It is also tested how far the craftsman can take this method to make the structure wind proof, and therefore warm to live in, since that’s the highest form of precision in log house building. LÄS MER
3. Framställning av multilagerfilmen AlN-HQ
Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : The method Atomic Layer Deposition, ALD, has been available since the 1970´s and it has opened the possibility to fabricate methods for inorganic thin films on a nanoscale. Later the interest for fabricating organic thin films with Molecular Layer Deposition, MLD, and controlling both the thickness and the composition of the film on a molecular scale. LÄS MER
4. Bridging the gap between food production and consumption : how alternative food networks forage the Berlin Foodscape
Master-uppsats, SLU/Department of Molecular SciencesSammanfattning : Venturing into bridging the gap between food production and consumption, metropolitan Alternative Food Networks (AFNs) are increasingly gaining momentum in the Global North. Nevertheless, people interested and participating in these initiatives form a rather homogenous group of highly educated and better-off consumers. LÄS MER
5. Study of HfN as seed layer for next generation of BAW RF filters : synthesis, characterization, and investigation of piezoelectric performance
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Micro-electro-mechanical systems (MEMS) have become an essential component of a wide range ofelectronic devices over the last decades such as accelerometers, microphones, gas sensors, and filters.During this new millennium, a new radio frequency (RF) technology has been developed to satisfy thetough demands that arose due to the implementation of 5G wireless communication: bulk acoustic wave(BAW) filters.
