  1. 1. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Aidas Urbonavicius; [2023]
    Nyckelord :ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER

  3. 2. In-situ Growth of Sn-seeded GaAs and GaSb Nanowire Heterostructures

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Azemina Kraina; [2023]
    Nyckelord :nanowire; heterostructure; ETEM; MOCVD; TEM; in-situ; Sn; GaAs; GaSb; materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : One of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effect' where Sb lingers in the system and nanowire.

  4. 3. 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

  5. 4. Investigations of p-type quantum dots in GaSb nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :In-Pyo Yeo; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. LÄS MER

  7. 5. Spatial control of electron & hole states in InAs/GaSb heterostructures

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Felix Vennberg; [2018]
    Nyckelord :InAs; GaSb; Nanowires; ambipolar; heterostructures; III-V; Physics and Astronomy;

    Sammanfattning : Single nanowire transistors employing three separately controlled electrostatic gates were fabricated to investigate band gap modulation in InAs-GaSb heterostructures. The aim is to show hybridization between electron and hole states over the heterojunction. LÄS MER
