催化金属栅气敏场效应器件的研究已有十多年了.通过使用催化金属栅的不同特性,目前已从最初的氢灵敏钯概场效应品体管(FET)发展了一类新的化学传感器,这些化学传感器不仅对氢敏感,而且对诸如乙醇、乙烯和氨等分子也灵敏,这些器件暴露于给定分子中时将 Catalytic metal-gate gas-sensing field-effect devices have been in development for more than a decade and have now developed a new class of chemistries from the original hydrogen-sensitive palladium field-effect transistors (FETs) through the use of different properties of catalytic metal gates These chemosensors are not only sensitive to hydrogen but are also sensitive to molecules such as ethanol, ethylene and ammonia, which when exposed to a given molecule
