1. Estudo das propriedades acusticas do filme finode TiO2 usando SAW / Study of acoustic properties of TiO2 films with help of surface acoustic wave resonators
This thesis presents the study and design of the elements which compose a gas sensor based on Surface Acoustic Wave technology, such as, SAW Colpitts oscillator and the SAW one-port resonator that are presents in the feedback loop of an amplifier. It was done deposition of TiO2 thin film different thickness on the sensor, in order to study the effect of SAW
