First Principles Theory and Fundamental Experiments on Active Materials for Naval Applications
Abstract
First Principles Theory and Fundamental Experiments on Active Materials for Naval ApplicationsAbstract:We propose to design and im"prove new active materials with applications in sensing, medicine, and energy using first-principles theory, synthesize these materi""als, and perform fundamental experiments to derive improved transducer materials for U.S. naval applications. The proposed research" program will concentrate on the effects of transition metal dopants and solid solutionsin polar materials. We will study the effec"ts of doping and ageing on ferroelectrics, study hyperferroelectrics, magnetoelectrics, and optimize transition-metal doped perovski"tes with giant electromechanical coupling for piezoelectric and possible magntetoelectric applications. A primary goal is to find materials with better performance per cost. This is best done by understanding the fundamental physics behind material performance and thereby developing design principles.
