This book was released on 2012-06-05 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas sensor products are very often the key to innovations in the fields of comfort, security, health, environment, and energy savings. This compendium focuses on what the research community labels as solid state gas sensors, where a gas directly changes the electrical properties of a solid, serving as the primary signal for the transducer. It starts with a visionary approach to how life in future buildings can benefit from the power of gas sensors. The requirements for various applications, such as for example the automotive industry, are then discussed in several chapters. Further contributions highlight current trends in new sensing principles, such as the use of nanomaterials and how to use new sensing principles for innovative applications in e.g. meteorology. So as to bring together the views of all the different groups needed to produce new gas sensing applications, renowned industrial and academic representatives report on their experiences and expectations in research, applications and industrialisation.

Download or read book Fabrication and Testing of Gas Sensors Based on Porous Silicon and Porous Silicon Carbide (3C-SiC) written by Dong Thanh Lieu and published by . This book was released on 2000 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Single crystalline cubic silicon carbide (3C-SiC) is one of the promising materials that can be used for high-power, high-frequency, and high-temperature devices. Thus, preparation of high quality single crystalline cubic silicon carbide and reproducible fabricated electronic devices based on 3C-SiC will have important technological impacts. In this thesis, we have developed a method for the fabrication of heterojunction Schottky diode gas sensors based on porous silicon and silicon carbide. Due to the large surface area of the porous layer, the adsorb gas species modify the I-V behavior of the Schottky diode or the silicon/silicon carbide heterojunction. It was found that the I-V behavior of the Schottky diodes strongly depends on the type of gases used. It was shown that a shift in the breakdown voltage ranging from I0V to 40V could be obtained depending on the structure of the gas sensor and the types of gas used. The porous silicon was made by anodization of p-type silicon using a mixture of hydrofluoric acid and ethanol. Chemical vapor deposition (CVD) was used to grow silicon carbide. Fourier Transform Infrared Spectroscopy (FTIR) and Secondary Ion Mass Spectrometry (SIMS) were used to verify the existence and stoichiometry of SiC in the prepared samples. X-Ray Diffraction and Transmission Electron Microscopy (TEM) were used to verify the crystalline structure of resulting SiC. Atomic Force Microscopy (AFM) tests were used to view the surface morphology of resulting samples.

Download or read book Physics, Chemistry and Technology of Solid State Gas Sensor Devices written by Andreas Mandelis and published by John Wiley & Sons. This book was released on 1993-10-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research and development of solid state gas sensor devices began in the 1950s with several uncoordinated independent efforts. The number and pace of these investigations later accelerated in response to increasing pressure placed on the environment and public health by industrial activities. Since 1970, several thousand articles have been written on the subject, and laboratories around the globe have introduced novel methodologies and devices to address needs associated with particular technological developments. Despite the rapid development of this important new technology, very little has been done to review and coordinate data related to sensor science and technology itself. Physics, Chemistry and Technology of Solid State Gas Sensor Devices focuses on the underlying principles of solid state sensor operation and reveals the rich fabric of interdisciplinary science that governs modern sensing devices. Beginning with some historical and scientific background, the text proceeds to a study of the interactions of gases with surfaces. Subsequent chapters present detailed information on the fabrication, performance, and application of a variety of sensors. Types of sensor devices discussed include: Gas-sensitive solid state semiconductor sensors Photonic and photoacoustic gas sensors Fiber optic sensors Piezoelectric quartz crystal microbalance sensors Surface acoustic wave sensors Pyroelectric and thermal sensors For analytical chemists using solid state sensors in environment-related analysis, and for electrical engineers working with solid state sensors, this book will expand and unify their understanding of these devices, both in theory and practice.

Download or read book Silicon Carbide Micro-devices for Combustion Gas Sensing Under Harsh Conditions written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A sensor based on the wide bandgap semiconductor, silicon carbide (SiC), has been developed for the detection of combustion products in power plant environments. The sensor is a catalytic gate field effect device, Pt/SiO2/SiC that can detect hydrogen-containing species in chemically reactive, high temperature (600 C) environments. We demonstrate that the device can be used as a hydrogen monitor in syngas applications of common interferants as well as sulfur and water vapor. These measurements were made in the Catalyst Screening Unit at NETL, Morgantown under atmospheric conditions. The sensor response to hydrogen gas at 350 C is 240 mV/decade, this is significantly higher than the device response to room temperature gas or that predicted from vacuum chamber studies. The enhanced catalytic activity of the platinum sensing film under energy plant operating conditions was investigated via AFM, x-ray diffraction, TEM and x-ray photoelectron spectroscopy. Our characterization indicated that exposure to high temperature gases significantly modifies the morphology of the Pt catalytic film and the Pt/SiO2 interfacial region, which we tentatively attribute to the enhanced hydrogen sensitivity of the sensing film. A model for the hydrogen/oxygen response of the SiC device under atmospheric conditions was developed. It is based on two independent phenomena: a chemically induced shift in the metal-semiconductor work function difference and the passivation/creation of charged states at the SiO2-SiC interface. The optimum operating set point for the SiC sensor with respect to response time and long term reliability was determined to be close to mid-gap. Ultrahigh vacuum (UHV) techniques were used to investigate the effects of sulfur contamination on the Pt gate. Exposure to hydrogen sulfide, even in the presence of hydrogen or oxygen at partial pressures of 20-600 times greater than the H2S level, rapidly coated the gate with a monolayer of sulfur. Although hydrogen exposure could not remove the adsorbed sulfur, oxygen was effective at removing sulfur with no evidence of irreversible changes in device behavior. The role of oxygen in the functioning of the SiC sensors was also investigated. All of the results are consistent with oxygen acting through its surface reactions with hydrogen, including the need for oxygen to reset the device to a fully hydrogen-depleted state and competition between hydrogen oxidation and hydrogen diffusion to metal/oxide interface sites. A strong sensor response to the unsaturated linear hydrocarbon propene (C3H6) was observed.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, the mainstream of microelectronics progression was mainly powered by Moore's law focusing on IC miniaturization down to nano scale. However, there is a fast increasing need for "More than Moore" (MtM) products and technology that are based upon or derived from silicon technologies, but do not simply scale with Moore’s law. This book provides new vision, strategy and guidance for the future technology and business development of micro/nanoelectronics.
