4. 2. Structure and morphology control of organic semiconductors for functional optoelectronic applications

   Author : Jenny Enevold; Ludvig Edman; Thomas Wågberg; Christian Müller; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; organic photonics; patterning; fullerene; polymerization; dimerization; spray-deposition; morphology; small molecule donor; high open-circuit voltage;

   Abstract : The functionality and application of organic semiconductors are largely dependent on their constituent structure and morphology. This thesis presents a number of functional and novel approaches for the control and tuning of structural and morphological features of a variety of organic semiconductor materials, and also demonstrates that these approaches can be utilized for improved device operation of field-effect transistors, organic solar cells and light-emitting electrochemical cells.

5. 3. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

   Author : Tripta Kamra; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. READ MORE

6. 4. 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
