    Microwave properties of tunable capacitors basee on magnetron sputtered ferroelectric Na0.5K0.5NbO3 film on low and high resistivity silicon substrates2001In: Integrated Ferroelectrics, ISSN 1058-4587, E-ISSN 1607-8489, Vol. 39, no 1-4, p. 359-366Article in journal (Refereed)
    Abstract [en]

    In this work, small signal DC voltage dependent dielectric permittivity, loss tangent, and tuneability of magnetron sputtered epitaxial Na0.5K0.5NO3 films are studied experimentally. (100)-oriented Na0.5K0.5NbO3 films are deposited onto SiO2-buffered CMOS grade low resistivity (p = 10-20 cm) and high resistivity (p = 15-45 kcm) silicon substrates. Planar capacitors with 2 or 4 m gaps between electrodes have been fabricated on top of ferroelectric films. These devices have been characterized in the frequency range 1.0 MHz to 50 GHz at temperatures 30 - 300K. Na0.5K0.5NbO3/SiO2/Si structures on high resistivity silicon substrate exhibit C-V performances typical for Metal-Insulator- Semiconductor (MIS) capacitors. At low frequencies, f 1.0 GHz, the large tuneability and large losses are associated with the MIS structure, while at higher microwave frequencies the tuneability is mainly associated with the ferroelectric, film. At 1.0 MHz and room temperature, the tuneability of Na0.5K0.5NbO3/SiO2/Si structures more than 90%, reducing to 10-15 % at 50 GHz. The losses decrease with increasing the DC bias and frequency. A Q-factor more than 15 at 50 GHz is observed. The dielectric permittivity of the Na0.5K0.5NbO3 film is in the range 50-150 at frequencies 0.045-50 GHz. On low resistivity substrate the performance of Na0.5K0.5NbO3 films is completely screened by the high losses in silicon, and the tuneability is negligible

    Competing pathways to sustainability?: Exploring conflicts over mine establishments in the Swedish mountain region2018In: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 218, p. 402-415Article in journal (Refereed)
    Abstract [en]

    Natural resource (NR) exploitation often gives rise to conflict. While most actors intend to manage collectively used places and their NRs sustainably, they may disagree about what this entails. This article accordingly explores the origin of NR conflicts by analysing them in terms of competing pathways to sustainability. By comparing conflicts over mine establishments in three places in northern Sweden, we specifically explore the role of place-based perceptions and experiences.

    The results indicate that the investigated conflicts go far beyond the question of metals and mines. The differences between pathways supporting mine establishment and those opposing it refer to fundamental ideas about human–nature relationships and sustainable development (SD). The study suggests that place-related parameters affect local interpretations of SD and mobilisation in ways that explain why resistance and conflict exist in some places but not others. A broader understanding of a particular conflict and its specific place-based trajectory may help uncover complex underlying reasons. However, our comparative analysis also demonstrates that mining conflicts in different places share certain characteristics. Consequently, a site-specific focus ought to be combined with attempts to compare, or map, conflicts at a larger scale to improve our understanding of when and how conflicts evolve. By addressing the underlying causes and origins of contestation, this study generates knowledge needed to address NR management conflicts effectively and legitimately.

    Konflikter om gruvetablering: Lokalsamhällets aktöreroch vägar till hållbarhet : slutrapport2016Report (Other academic)
    Abstract [sv]

    Gruvprospektering och gruvetablering kan ge upphov tilllokala konflikter. Syftet med den här studien är att undersökahur berörda aktörer och medborgare ser på fråganom framtida mineralutvinning och gruvetablering, vilketutrymme som finns för lokalt deltagande och inflytandei politik och regelverk, samt möjligheterna att hanteraeventuella konflikter med hjälp av dialog och samråd. Vihar analyserat tre gruvetableringsprocesser på tre olikaplatser i det fjällnära området: järnbrytning i Gállok/Kallak(Jokkmokks kommun), nickelutvinning i Rönnbäck/Rönnbäcken (Storumans kommun) samt guld, koppar ochjärnbrytning i Rakkuri (Kiruna kommun).
