This thesis focuses on the fundamental understanding of the crystallographic nature, domain structure and domain dynamics of KNN. Since compositions close to x = 0.5 are of primary interest because of their superior piezoelectric activity among other compositions (0 < x < 1), detailed crystallographic and domain structure studies were conducted to provide explanation for the observed electromechanical response. Investigations were conducted on random, textured and single crystals to collect comprehensive information for elucidating the fundamental behavior. (Abstract shortened by ProQuest.)
