This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this dissertation is on creating electronic devices that utilize unique charge storage properties of redox-active organic molecules for memory applications. A hybrid silicon-molecular approach has been adopted to make use of the advantages of the existing silicon technology, as well as to study and exploit the interaction between the organic molecules and the bulk semiconductor. As technology heads into the nano regime, this hybrid approach may prove to be the bridge between the existing Si-only technology and a future molecule-only technology. Functionalized monolayers of redox-active molecules were formed on silicon surfaces of different doping types and densities. Electrolyte-molecule-silicon test structures were electrically characterized and studied using cyclic voltammetry and impedance spectroscopy techniques. The dependence of the oxidation and reduction processes on the silicon doping type and density were analyzed and explained using voltage balance equations and surface potentials of silicon. The role played by the silicon substrate on the operation of these memory devices was identified. Multiple bits in a single cell were achieved using either molecules exhibiting multiple stable redox states or mixed monolayer of different molecules. Self-assembled monolayers of redox-active molecules were also incorporated on varying thickness of silicon dioxide on n- and p- silicon substrates in an attempt to create non-volatile memory. The dependences of read/write/erase voltages and retention times of these devices were correlated to the SiO2 thickness by using a combination of Butler-Volmer and semiconductor theories. The region of operation of the silicon surface (accumulation, depletion or inversion) and the extent of tunneling current through the silicon dioxide were found to influence the charging and discharging of the molecules in the monolayer. Increased retention times due to the presence of SiO2 can be useful in realizing non-volatile memorie.

Available in PDF, EPUB and Kindle. Book excerpt: Redox reactions are central to the major element cycling, many cell cycles, many chemisorption and physisorption processes, trace element mobility from rocks and sediments toward wells, aquifers, trace element toxicity toward life forms, and most remediation schemes including water treatments; over the last three decades, the field has attracted a lot of scientists, and a great deal of researches has been done in redox chemistry. This book provides a very broad overview of the state of the art of understanding redox processes, which starts with giving a concise introduction that describes the origin, historical background, and the development of the redox definitions. The book is organized into two sections that include ten chapters and introduces, in Section 1, generalized electron balance theory and its applications in electrolytic redox systems, redox-active molecules and its applications in device memory, fundamentals and applications of flow batteries and their integration into antidirect current, and donor acceptor titrations of displacement and electronic transference. Section 2 introduces redox in biological processes, including roles of reactive oxygen species in respiration, metabolism, and regulations, and redox in physiological processes as redox-sensitive TRP channels TRPA1 and TRPM2. All chapters are written by different authors (with the exception of Chapter 1 [Introduction]). This clearly reflects the broad range of topics that have been covered by experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: As CMOS technology extends to and beyond 65-nm technology node, many challenges to MOSFET were raised. The industrial and academic communities are aggressively searching for solutions to meet these challenges: (1) non-classical CMOS to extend the life of CMOS technology, and (2) fundamentally new technologies to replace CMOS technology including molecular electronics. The approach of hybrid silicon/molecular electronics is to provide a smooth transition technology by integrating molecular intrinsic scalability and diverse properties with the vast infrastructure of traditional MOS technology. The focus of this research is on integrating redox-active, organic molecules into Si-based structures to first, characterize and understand the properties of molecules; second, generate a new class of hybrid silicon/molecular devices for memory applications; and third, open a new way to develop purely molecular-scale devices. This dissertation has concentrated on the fabrication, characterization and simulation of hybrid CMOS/molecular devices for memory applications: (1) Specific procedures have been successfully developed for attaching redox-active, tightly-bonded, well-packed, molecular self-assembled monolayers on Si and SiO2 surfaces via solution-phase or vapor-phase deposition. (2) An electrolyte/molecule/Si structure has been implemented for electrical characterizations and theoretical simulations to understand the molecules and their application in memory devices, including DRAM and FLASH devices. (3) Two different strategies to achieve multibit memory have been developed and optimized using the methods of attaching mixed monolayers and stacked multilayer films. (4) Molecular multilayer films with very high surface coverage have been achieved for application in memory devices. Metal/molecule/Si sandwich structures using molecular multilayer films were fabricated and exhibited nonvolatile electrical switching properties. A set of control experiments indicate that these sw.

Verani Major: Chemistry (Inorganic) Degree: Doctor of Philosophy The silicon-based microelectronic industry has made remarkable technological advancements. Among these, new generation consumer electronics, telecommunication devices, and high performance data processing smart devices are of special interest. At present, electronic components existing on a single silicon chip grow rapidly, and soon the miniaturization process of electrical components will face limitations due to heat dissipation. Therefore, as an advanced alternative for silicon-based electronic components, the investigation of nanoscale molecular electronic devices is of great importance. This dissertation research is focused on the development of redox-active asymmetric metallosurfactants as potential candidates for molecule-based electronics. Asymmetric donor-acceptor type [D-A] molecules are promising candidates to study the current rectification behavior. In order to address this phenomenon, a series of ligands with phenolate moieties and, their gallium(III), iron(III), and manganese(III) complexes with [N2O3] and [N2O2] coordination environments were synthesized and structurally characterized using multiple methods. Ligands were designed with different electron-donating and electron-withdrawing substituents, to modulate structural, chemical, and physical properties, such as geometry, spectroscopic, redox, film formation, and electrical properties. As an initial attempt, low symmetry gallium(III) and iron(III) complexes with [N2O3] binding moieties were developed. Different alkyl substituents are introduced to the phenylenediamine moiety of the main ligand structure to allow for film formation of the metal complexes. The electrochemical properties of gallium(III) complexes show ligand-based redox processes, while the iron(III) complexes show metal- and ligand-centered redox processes.
