  2. 6. Aerosol Metal Nanoparticles and their Role in Particle-Assisted Growth of III–V Nanowires

    Author : Robert Hallberg; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol formation; III–V semiconductor materials; catalyst particles; Palladium nanoparticles; Gold nanoparticles; Spark discharge generation; MOVPE; MOCVD; Transmission electron microscopy TEM ; Phase stability; Nanoparticle deposition; Nanoparticle generation; nanoparticles characterization; Nanowire NW ; Nanowire growth;

    Abstract : Semiconductor nanowires have properties that make them potentially useful for applications in future electronic, photovoltaic, and optoelectronic devices. A powerful nanowire fabrication technique is the use of a nanoparticle as a preferential nucleation site, from which a nanowire grows. READ MORE

  4. 7. In-situ Study of the Growth, Composition and Morphology of III-V Semiconductor Nanowires

    Author : Robin Sjökvist; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Semiconductor; III-V; Transmission Electron Microscopy; In-situ; Environmental TEM; Crystal growth;

    Abstract : It is widely known that nanoparticle seeded growth of III-V semiconductor nanowires often occurs via the vapor-liquid-solid mechanism. However, conventional growth of nanowires is carried out in closed systems, where mostof the details and dynamics of the growth are impossible to follow. READ MORE

  5. 8. Understanding the Role of Seed Particle Material on III-As Nanowire Growth

    Author : Rong Sun; Fasta tillståndets fysik; []
    Keywords : seminconductor materials; nanowire growth; catalyst; metalorganic vapor phase epitaxy MOVPE ; Tin; Fysicumarkivet A:2018:Sun;

    Abstract : III-V semiconductor nanowires have attracted extensive research interests over the past few decades due to their unique geometry and great potential for promoting new functionalities in future electronics, light-emitting diodes and solar cells. However, in order to push this technology beyond the laboratory level, it is essential to combine it with the current Si-based semiconductor industry for affordable production. READ MORE
