This book was released on 1998 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, a systematic study involving the fabrication of thin film SnO2 gas sensors by sol-gel technique had been carried out. The sol solution of SnO2 was prepared by chemical synthesis process. Tin tetrachloride and sodium ethoxide were used as the fundamental reactants. The synthesis sol had been coated on the glass substrate by spin coating technique to form thin films. The coated films were then subjected to anneal at 550 C for 1 hour to change their structure to SnO2. It was found that the thickness of SnO2 films could be linearly controlled by varying the number of coatings. The thickness of each coating was about 350 A. In order to analyze the gas sensing performance quantitatively, a novel gas measuring circuit was proposed. This circuit could be used to calculate sensitivity and recovery time without depending on the external circuit components such as resistance. The performance of this proposed circuit had been compared with that of the conventional circuit in both theoretical and experiment aspects. The results indicated the conventional measuring circuit is not suitable for calculating gas sensitivity in the case which a semiconductor gas sensor under test has a nonlinear I-V characteristic. For the proposed sircuit, this nonlinear property did not cause any problem in calculating sensitivity. Moreover, the gas sensing performance of various gas sensors could be compared quantitatively if the bias voltage of all gas sensors were set to the same value. The characterization of the fabricating gas sensors had been performed on a flow injection system combining with the proposed measuring circuit. The sensitivity of gas sensor had been found to be strongly dependent on the film thickness. The experiments showed that the optimum thickness was about 1000 A. From the gas response tests to alcohol and ammonia solutions, it was found that the unmodified SnO2 gas sensor gave the highest sensitivity. The addition of some modified substances such as CuSO4, AgNO3 and Au reduced the gas sensitivity. However, there was a tendency to increase sensitivity by adding FeCl3. By using the power law model to analyze the change of sensitivity with sample concentration, it was found that the unmodified SnO2 gas sensor could be used to detect alcohol and ammonia in the range of 0.08-10 and 0.05-10% by volume respectively. The optimum operating temperature was 250 C for alcohol detection and 350 C ammonia detection.

Download or read book Indium Tin Oxide (ITO) Deposition, Patterning, and Schottky Contact Fabrication written by Jianming Zhou and published by . This book was released on 2006 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As a transparent conductive material, indium tin oxide (ITO) has been utilized as electrodes in liquid crystal displays, solar cells, heat reflecting films and gas sensors. In general, the desired properties are high conductance and transmission. However, due to the complexity of ITO, the film properties strongly depend on the deposition processes. In this study, the deposition conditions for ITO film were optimized to get both high conductivity and transmission. The emphasis was on investigating the effects of various deposition parameters, such as oxygen partial pressure, total gas flow, annealing conditions and power. These are the most critical parameters for ITO deposition. A mathematical model to describe the material properties as functions of these parameters for a CVC model 601 Sputterer was developed utilizing JMP IN software. Films with resistivity 3x10-4[omega]-cm and transmittance above 90% were achieved on glass and silicon substrates with 20 hours of annealing. The processing window (power: 120-150W, oxygen ratio: 6-10%) is, to the author's knowledge, the largest reported by literature. However, the ITO film properties (electrical and optical) variation between runs needs to be further reduced. Patterning of ITO was also investigated. High but controllable etch rates are desired. Both wet and dry etch processes were developed. The etch rate of 48nm/min was achieved by using HCL aqueous solution (4:1 HCl to DI water volumetric ratio, where HCl is the standard 37% HCl solution) with almost infinite selectivity between the ITO film and the photoresisit. For dry etch, the etch rate is 1nm/min with just argon as the working gas and the etching selectivity between the photoresist and the ITO film is 13.02. To etch 100nm ITO film, the photoresist needs to be at least 1.5um to serve as etching mask. This dry etch process still needs to be improved. A Schottky contact was successfully fabricated by using ITO as the metal. The electrical barrier height was calculated to be 1.01eV. The current-voltage characteristics were investigated as well"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Nanosensors for Smart Manufacturing provides information on the fundamental design concepts and emerging applications of nanosensors in smart manufacturing processes. In smart production, if the products and machines are integrated, embedded, or equipped with sensors, the system can immediately collect the current operating parameters, predict the product quality, and then feed back the optimal parameters to machines in the production line. In this regard, smart sensors and their wireless networks are important components of smart manufacturing. Nanomaterials-based sensors (nanosensors) offer several advantages over their microscale counterparts, including lower power consumption, fast response time, high sensitivity, lower concentration of analytes, and smaller interaction distance between sensors and products. With the support of artificial intelligence (AI) tools such as fuzzy logic, genetic algorithms, neural networks, and ambient intelligence, sensor systems have become smarter. This is an important reference source for materials scientists and engineers who want to learn more about how nanoscale sensors can enhance smart manufacturing techniques and processes. - Outlines the smart nanosensor classes used in manufacturing applications - Shows how nanosensors are being used to make more efficient manufacturing systems - Assesses the major obstacles to designing nanosensor-based manufacturing systems at an industrial scale
