Abstract :
In this paper, we present a surface acoustic wave (SAW) gas sensor based on nano-structured molybdenum oxide (MoOx) thin film. The film was deposited onto a 36deg YX LiTaO3 SAW transducer, with an operating frequency of approximately 103 MHz, by thermal evaporation. The nanostructured MoOx film consists of connected nanorods with diameters of less than 100 nm. We compared devices with MoOx deposited by RF sputtering and thermal evaporation and found those with evaporated films have response that are an order of magnitude larger.
