2. 1. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

   Author : Axel Persson; -lup-obsolete; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

   Abstract : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). READ MORE

4. 2. Understanding and Optimization of III-V nanowire growth in Aerotaxy

   Author : Sudhakar Sivakumar; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor materials; Nanowires; Aerotaxy; Fysicumarkivet A:2021:Sivakumar;

   Abstract : III-V semiconductor nanowires are high aspect ratio nanostructures with superior properties that can potentially enhance the functionality of next-generation opto-electronic devices. At present, the most reliable method for fabricating III-V semiconductor nanowires is the particle-assisted vapor-liquid-solid growth using a substrate-based growth process. READ MORE

6. 4. Growth of Semiconductor Nanowires for Solar Cell Applications

   Author : Magnus Heurlin; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOVPE; Aerotaxy; III-V semiconductor materials; nanowire; solar cells; photovoltaics; Fysicumarkivet A:2015:Heurlin;

   Abstract : Nanowires have the ability to absorb light much more efficient than conventional thin film layers. This makes them candidates for the development of new types of solar cells that have higher efficiency and lower material usage than current technologies. READ MORE

7. 5. Transmission Electron Tomography and In-situ Analysis of Nanowires

   Author : Axel Persson; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy TEM ; Electron tomography; Nanowires NWs ; Aerotaxy; In-situ;

   Abstract : As semiconducting nanowires have promising applications for materials science, nanoelectronics and photovoltaic devices, absolute control of their structure, morphology and composition is a prerequisite for their functionality. Nanowires, grown through the vapor-liquid-solid (VLS) method, exhibit a complex relationship between their liquid seed particle and what properties, such as the aforementioned ones, the wire adopts in the end.
