  • Understanding of Ferroelectric to Relaxor Phenomenon in Bismuth-based Perovskite

    Creator:
    Gupta, Sanu K.
    Abstract:
    It has been well established that ferroelectric to relaxor crossover in piezoelectric ceramics exhibit promising electromechanical and dielectric properties over a wide temperature range, applying sensors and actuators transducers and such. A plethora of research has reported giant strain in various lead-free piezoelectric ceramics and attributed the reasoning to the...

  • Defect Mechanisms in Bismuth-based Perovskites

    Creator:
    Kumar, Nitish
    Abstract:
    The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...
