  1. 1. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  3. 2. Characterization of the cobalt content in zinc ore from Zinkgruvan, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ingeborg Hjorth; [2022]
    Keywords : Zinkgruvan; Bergslagen; Cobalt; Sphalerite; Pyrrhotite; Safflorite;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. READ MORE

  4. 3. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Dino Leopardi; [2020]
    Keywords : Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Abstract : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. READ MORE

  5. 4. Genetic relationships and origin of the Ädelfors gold deposits in Southeastern Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Tobias Wiberg Steen; [2018]
    Keywords : Ädelfors; sulfur isotope ratio; pyrite chemistry; orogenic gold; gold; gold quartz vein; trace elements; gold mine; banded iron formation; SEM-EDS analysis; gold silver ratio; Ädelfors; svavelisotoper; pyritkemi; orogent guld; guldrik kvartsåder; guld; guldfyndighet; spårelement; bandad järnmalm; SEM-EDS analys; guld silver förhållande;

    Abstract : Ädelfors is situated ca 17 km east of Vetlanda, Jönköping County, in the N-S striking Trans-scandinavian igneous belt and is a part of the NE-SW striking 1.83-1.82 Ga Oskarshamn-Jönköping belt emplaced during a continental subduction towards the Svecofennian continental margin. The continental arc hosts the 1. READ MORE

  6. 5. Rb-Sr sphalerite data and implications for the source and timing of Pb-Zn deposits at the Caledonian margin in Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alfred Larsson; [2018]
    Keywords : Laisvall; Granberget; geochronology; sphalerite; ore; Rb-Sr; Earth and Environmental Sciences;

    Abstract : The eastern Caledonian erosional front hosts the world-class Pb-Zn deposit at Laisvall (64 Mt mined) and Granberget mineralization, northern Sweden, along with several other smaller, related types of deposits consisting of impregnation mineralization of galena and sphalerite in clastic host rocks. Previous work have discussed the nature of the ore-forming processes and constraints for the timing of the mineralization, however, the mechanisms are still not fully understood and previous age determinations are ambiguous.
