Book Description :

Solution Processed Metal Oxide Thin Films for Electronic Applications discusses the fundamentals of solution processing materials chemistry techniques applied to metal oxide materials systems for key device applications. With the solution form of metal oxides or inks, direct patterning can be done by printing techniques instead of lithographic patterning, making the fabrication process more simple and efficient than other processes. The book introduces the basic information (materials properties, materials synthesis, barriers) about the most relevant metal oxide materials that have been widely used in electronics. The second part is devoted to ink formulation and solution processing methods including sol-gel processing, surface functionalization aspects, and more. There is also a comprehensive account of the electronic applications of solution processed metal oxide films, including thin film transistors, photovoltaic cells and other electronics devices and circuits. This is an important reference for those interested in oxide electronics, printed electronics, flexible electronics or large-area electronics.

Book Description :

Metal oxide nanomaterials exhibit interesting electrical and photochemical properties because of their size, stability, and high surface area that render them as great choices in fabricating alternative electrode materials for electrochemical energy storage and sensor applications. The hybridization of metal oxides with other materials lead to the improvement in electrical conductivity, stability, and electron transfer kinetics during the electrocatalytic reactions. These key factors result in greater sensitivity of the sensor materials towards the analyte molecules. This book reviews the electrochemical determination of a variety of toxic chemical contaminants using metal oxide-based nanocomposite materials. Ultrasensitive and selective detection of toxic chemical contaminants is important and demanding, especially for monitoring and controlling environmental pollution. In recent years, metal oxide-based nanocomposite materials have shown high potential in the electrochemical detection of heavy metals, inorganic anions, phenolic compounds, pesticides, and chemical warfare reagents. Metal Oxides in Nanocomposite-Based Electrochemical Sensors for Toxic Chemicals comprehensively reviews this topic. In addition to the instrumental simplicity, the electrochemical methods show the improved sensor performance through the synergetic effect of metal oxide and other electroactive nanomaterial present in the nanocomposite. Thus, detailed information on the electrochemical sensing of toxic chemical contaminants using metal oxide-based nanomaterials are discussed. The recent progress in developing electrochemical sensors using metal oxide-based nanocomposite materials and perspectives on future opportunities in sensor research and development are addressed in the book.

Book Description :

Primarily used as transparent electrodes in solar-cells, more recently, physical vapor deposited (PVD) transparent conductive oxide (TCO) materials (e.g. ZnO, In2O3 and SnO2) also serve as the active layer in thin-film transistor (TFT) technology for modern liquidcrystal displays. Relative to a-Si:H and organic TFTs, commercial TCO TFTs have reduced off-state leakage and higher on-state currents. Additionally, since they are transparent, they have the added potential to enable fully transparent TFTs which can potentially improve the power efficiency of existing displays. In addition to PVD, solution-processing is an alternative route to the production of displays and other large-area electronics. The primary advantage of solution-processing is in the ability to deposit materials at reduced-temperatures on lower-cost substrates (e.g. glass, plastics, paper, metal foils) at high speeds and over large areas. The versatility offered by solution-processing is unlike any conventional deposition process making it a highly attractive emergent technology. Unfortunately, the benefits of solution-processing are often overshadowed by a dramatic reduction in material quality relative to films produced by conventional PVD methods. Consequently, there is a need to develop methods that improve the electronic performance of solution-processed materials. Ideally, this goal can be met while maintaining relatively low processing temperatures so as to ensure compatibility with low-cost roll-compatible substrates. Mobility is a commonly used metric for assessing the electronic performance of semiconductors in terms of charge transport. It is commonly observed that TCO materials exhibit significantly higher field-effect mobility when used in conjunction with high-k gate dielectrics (10 to 100 cm2 V−1 s −1 ) as opposed to conventional thermally-grown SiO2 (0.1 to 20 cm2 V−1 s −1 ). Despite the large amount of empirical data documenting this bizarre effect, its physical ori- 2 gin is poorly understood. In this work, the interaction between semiconductor TCO films and high-k dielectrics is studied with the goal of developing a theory explaining the observed mobility enhancement. Electrical investigation suggests that the mobility enhancement is due to an effective doping of the TCO by the high-k dielectric, facilitated by donor-like defect states inadvertently introduced into the dielectric during processing. The effect these states have on electron transport in the TCO is assessed based on experimental data and electrostatic simulations and is found to correlate with negative aspects of TFT behavior (e.g. frequency dispersion, gate leakage, hysteresis, and poor bias stability). Based on these findings, we demonstrate the use of an improved device structure, analogous to the concept of modulation doping, which uses the high-k dielectric film as an encapsulate, rather than a gate-dielectric, to achieve a similar doping effect. In doing so, the enhanced mobility of the TCO/high-k interface is retained while simultaneously eliminating the negative drawbacks associated with the presence of charged defects in the gate dielectrics (e.g. frequency dispersion, gate leakage, hysteresis, and poor bias stability). This demonstrates improved understanding of the role of solution-processed high-k dielectrics in field-effect devices as well as provides a practical method to overcome the performance degradation incurred through the use of low-temperature solution-processed TCOs.
