  2. 1. In-situ TEM Probing of Nanomaterials

    Author : Magnus Hummelgård; Håkan Olin; Valeria Nicolosi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; in situ; TEM; probing; nanowires; nanoparticles; ink; Other engineering physics; Övrig teknisk fysik; Material physics with surface physics; Materialfysik med ytfysik; Condensed matter physics; Kondenserade materiens fysik;

    Abstract : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. READ MORE

    Abstract : With the ongoing miniaturisation of devices, the interest in characterising nanoscale physical properties has strongly increased. To further advance the field of nanotechnology new scientific tools are required. READ MORE

  5. 3. 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.
