• W35722275 abstract "Looking at the literature about chemical sensors, it is evident that numerous sensor effects are reported but only a very few sensor concepts remain, which are suitable for industrial applications. This is in contrast to the measurement of physical parameters such as pressure, temperature, acceleration etc. There are several reasons for this discrepancy. First of all, for chemical reactions usually there exist much more cross correlations, which have to be considered in order to determine a correct concentration of chemical species, and secondly, environmental influences cannot be neglected at all. Therefore, it becomes extremely difficult to fulfill all the requirements, which have been listed in the introduction of this paper. One interesting and successful gas sensor concept is based on the measurement of surface work function changes due to chemical reactions. Besides a Kelvin probe with a vibrating capacitance, field effect transistors (FET) are well suited to act as transducers for the determination of the corresponding potential variations. This chapter reviews the detection mechanisms, which lead to work function changes and gives an overview of the various transducer concepts. Beginning with the so-called Lundström FET, the historical development all the way to the hybrid mounted “floating gate FET (FG-FET)” is presented. This latest concept is extremely flexible and depending on the chemical-sensitive layer, it can be used for the detection of a large variety of gases. As an example the development of a hydrogen sensor for future automotive application is presented in more detail. Using platinum as chemical-sensitive layer it is shown that under harsh environmental conditions, it is not sufficient to consider exclusively the reaction of hydrogen with the platinum, but rather, it is necessary to also take into account oxygen, which is always present in air. As a result, a characteristic catalytic ignition point, i.e., the adsorbed hydrogen atoms are consumed by a water-forming reaction, occurs at around 60°C. Only if the complete reaction scheme is considered, it is possible to understand the complex and partially intriguing transducer signals. The development of two-layer systems for the chemical-sensitive layer solves these problems by using a phase transition that comes along with the catalytic ignition and allows a stable sensor operation in the required temperature regime between −40°C and +120°C. Based on the theoretical modeling the temperature-dependent phase transition has been evaluated in order to measure hydrogen concentration up to 4% with high accuracy and to fulfill the automotive requirements. Finally, in the last section, a new GasFET concept is presented, which extends the operating regime to temperatures as high as 400°C. In the future, this allows the incorporation of a variety of new gas-sensing materials, which need temperatures above 200°C in order to show a decent adsorption–desorption equilibrium. Altogether, it has been proven that GasFETs are a very promising candidate for future industrial applications." @default.
