This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functionalization of oxide-free silicon and silicon oxide surfaces is important for a number of applications. In this work, organic monolayers are grafted (GOM) on oxide-free silicon surfaces using thermal and ultraviolet-activated hydrosilylation of hydrogen-terminated silicon surfaces, primarily using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy for characterization. The resulting amine-terminated GOM have been used for depositing nanoparticles, selecting the end group for two very specific applications: single electron devices and nano-quantum-dot (NQD) enhanced Si photovoltaic cells. To perform single-electron transport measurements, colloidal gold nanoparticles have been deposited on amine-functionalized silicon surfaces and tunneling measurements performed with a scanning tunneling microscope in an ultra-high vacuum chamber. Using a double-barrier tunneling junction (with the GOM as the first barrier and the vacuum between the scanning tip and the gold nanoparticle as the second one), single-electron transport was observed at 30K through a Coulomb staircase phenomenon. The critical parameters were identified to improve reproducibility. Finally, recently developed advanced modeling, based on traditional "orthodox" theory, was optimized to account for the observations (e.g. I-V dependence on band bending). This work provides a basis for the development of single-electron transistors that are compatible with current silicon based technology. To enhance standard silicon-based solar cells, GOM is also needed to graft strongly absorbing II-VI NQDs and optimize their energy transfer to the silicon substrate. Recent photoluminescence spectroscopy has demonstrated that energy transfer occurs through both radiative and non-radiative mechanisms between NQDs and the substrate. With grafting technology, the aim was to optimize absorption, as probed by photoluminescence, in two ways. First, silicon nanopillars were fabricated to increase the surface area, with a careful investigation of the attachment of the NQDs to the walls of the nanopillars. Second, multilayers were deposited, using a diamine linker between layers. In the case of bilayers of NQDs with a size gradient, the PL measurements confirm directed energy transfer from the top to the second layer and then to the substrate. These two approaches are shown to increase the efficiency of energy transfer of current Si solar cells, and will require more work to implement in actual device fabrication

This book was released on 2003 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major goal of this research is to understand design principles of interfaces, suitable for the reconstitution the ion channel membrane proteins. In the present work, we focused on the immobilization of two channel proteins, [alpha]-Hemolysin from Staphylococcus aureus and Mechanosensitive Ion Channel of Large Conductance (MscL) from Salmonella typhimurium, onto single crystal silicon substrates (silicon wafers). High-resolution atomic force microscopy (AFM) was utilized as a tool for the monitoring of the molecular conformations of the ion channels after immobilization. As observed, [alpha]-Hemolysin was adsorbed onto bare silicon in collapsed state, while adsorption of MscL resulted in unraveling of the protein. LB deposition of proteins embedded in lipid monolayer reduced denaturation of the proteins on silicon surface, due to reduced surface energy. Octadecyltimethoxy silane (ODTMS) self-assembled monolayers (SAMs) were used as a "buffer layer analog" of a lipid membrane. MscL was successfully reconstituted in these organic SAMs. Analysis of dimensions of the MscL displayed that the gating state and the molecular conformation of SAM-supported MscL can be controlled by variation of the surface energy of the supporting surface layer. Closed, intermediate, and open states were observed on surfaces with different surface tensions. Obtained results demonstrated an agreement with known molecular modeling data for gating mechanisms of the MscL protein in lipid membrane.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents both fundamental knowledge and latest achievements of this rapidly growing field in the last decade. It presents a complete and concise picture of the the state-of-the-art in the field, encompassing the most active international research groups in the world. Led by contributions from leading global research groups, the book discusses the functionalization of semiconductor surface. Dry organic reactions in vacuum and wet organic chemistry in solution are two major categories of strategies for functionalization that will be described. The growth of multilayer-molecular architectures on the formed organic monolayers will be documented. The immobilization of biomolecules such as DNA on organic layers chemically attached to semiconductor surfaces will be introduced. The patterning of complex structures of organic layers and metallic nanoclusters toward sensing techniques will be presented as well.

Download or read book Hydrosilylation written by Bogdan Marciniec and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: For fifty years, Hydrosilylation has been one of the most fundamental and elegant methods for the laboratory and industrial synthesis of organosilicon and silicon related compounds. Despite the intensive research and continued interest generated by organosilicon compounds, no comprehensive book incorporating its various aspects has been published this century. The aim of this book is to comprehensively review the advances of hydrosilylation processes since 1990. The survey of the literature published over the last two decades enables the authors to discuss the most recent aspects of hydrosilylation advances (catalytic and synthetic) and to elucidate the reaction mechanism for the given catalyst used and the reaction utilization. New catalytic pathways under optimum conditions necessary for efficient synthesis of organosilicon compounds are presented. This monograph shows the extensive development in the application of hydrosilylation in organic and asymmetric syntheses and in polymer and material science.

This book was released on 2011-12-02 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has experienced a rapid growth in the past decade, largely owing to the rapid advances in nanofabrication techniques employed to fabricate nano-devices. Nanofabrication can be divided into two categories: "bottom up" approach using chemical synthesis or self assembly, and "top down" approach using nanolithography, thin film deposition and etching techniques. Both topics are covered, though with a focus on the second category. This book contains twenty nine chapters and aims to provide the fundamentals and recent advances of nanofabrication techniques, as well as its device applications. Most chapters focus on in-depth studies of a particular research field, and are thus targeted for researchers, though some chapters focus on the basics of lithographic techniques accessible for upper year undergraduate students. Divided into five parts, this book covers electron beam, focused ion beam, nanoimprint, deep and extreme UV, X-ray, scanning probe, interference, two-photon, and nanosphere lithography.
