dc.description.abstractWe have been investigating CaCu₃Ti₄O₁₂ class of perovskites for variety of applications due to its very large dielectric constant. Several mechanisms have been proposed for the existence of the high dielectric constant based on grain boundaries and oxygen deficiencies. We will report the results of the effects of monovalent substitution to replace calcium. This will alter the size to distort the perovskite structure. In addition, we used this system as a sensor for organic agents. There were very large changes in dielectric constant and resistivity indicating this system as a very good sensor material.en_US
