Abstract Scope |
The perovskites are very important class of materials for variety of applications. To meet the demands for the tunable devices and high dielectric parallel plate capacitors, several perovskites have been studied extensively. In spite of great progress in processing, low resistivity and process driven variables in properties remain a big hurdle for its wide range of applications as a dielectric capacitor. We observed that effect of chemicals used in wet and semi wet affected dielectric and other semiconducting properties. With these goals, we used the parallel plate capacitors as chemical and biological sensors. The data indicated huge difference in the dielectric and resistivity of the exposed samples. This indicates that perovskites can be used for chemical and biological sensors at very low cost. Preliminary data indicates that after exposing in atmosphere, there materials can recover to original characteristics. |
