1. Making space for resilient urban well-being
Sammanfattning : This thesis addresses the need for urban landscapes that provide resilient contributions to inhabitants’ well-being while also limiting impacts on the Earth system. It aims to (1) advance a nuanced understanding of how urban environments relate to urban dwellers’ well-being, and (2) formulate guidelines for planning that supports urban dwellers’ well-being and align with global sustainability.

2. MOCVD growth of GaN-based high electron mobility transistor structures
Sammanfattning : The present work was to improve the overall quality of GaN-based high electron mobility transistor (HEMT) epitaxial structures grown on semi-insulating (SI) SiC and native GaN substrates, using an approach called bottom-to-top optimization. The bottom-to-top optimization means an entire growth process optimization, from in-situ substrate pretreatment to the epitaxial growth and then the cooling process. LÄS MER
3. ZrB2 Thin Films : Growth and Characterization
Sammanfattning : Zirconium diboride, ZrB2, is a ceramic material with bulk properties such as high melting point (3245 °C), high hardness (23 GPa), and low resistivity (~8 μΩcm). Thin film growth of ZrB2 using physical vapor deposition has suffered from problems with films deviating from stoichiometry and with high levels of contaminants, especially high oxygen content.

4. Spatial analyses of people's experiences in urban landscapes
Sammanfattning : Limiting cities’ negative impact for global sustainability suggests compact city development. However, extensive and accessible urban nature is important for urban dwellers’ wellbeing. Aligning efforts to make cities locally and globally sustainable means resolving this conflict. LÄS MER
