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

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

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

    Sammanfattning : 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. LÄS MER

  3. 17. Quasicrystal nanowires in SNS-junctions

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Anna Sandberg; [2022]
    Nyckelord :quasicrystal; Fibonacci quasicrystal; superconductivity; SNS-junction; Josephson junction; proximity effect; Josephson current; Bogoliubov-de Gennes method;

    Sammanfattning : Quasicrystals are systems that are ordered but not periodic. They do however still have long-range order and well-defined diffraction peaks. This leads to interesting properties, like critical states which are neither extended nor localized, and to topological invariants and edge states. LÄS MER

  4. 18. Single Photon LSCM in the NIR Range

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Klara Wallenbro; [2022]
    Nyckelord :LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

    Sammanfattning : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

  5. 19. Fabrication Development of InAs-Pb Nanodevices

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Bo Rasmus Edholm; [2022]
    Nyckelord :Nanofabrication; Qubit; InAs; SAG; Nanowire; Lithography; EBL;

    Sammanfattning : Research groups around the world are looking to develop a qubit protected from decoherence for achieving quantum advantage in computations. This would have huge impact on the modern world. The applications are many from drug development to cryptography and many more  elds. LÄS MER

  7. 20. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Patrik Blomberg; Ludvig Pile; [2022]
    Nyckelord :D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

    Sammanfattning : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. LÄS MER
