Abstract:
A systematic method for selecting actuators (devices which produce a controlled force or displacement) for a given application is developed. Performance characteristics for several classes of actuator are presented in a graphical form which allows the characteristics of the actuator to be matched to the requirements of tasks. Some conclusions are drawn regarding the suitability of ferroelectric actuators for various tasks, and the opportunity offered by the non-linear, high force and high displacement regime of behaviour in ferroelectrics.

Abstract:
A key non-destructive technique for analysis, optimization and developing of new functional materials such as sensors, transducers, electro-optical and memory devices is presented. The Thermal-Pulse Tomography (TPT) provides high-resolution three-dimensional images of electric field and polarization distribution in a material. This thermal technique use a pulsed heating by means of focused laser light which is absorbed by opaque electrodes. The diffusion of the heat causes changes in the sample geometry, generating a short-circuit current or change in surface potential, which contains informat

Abstract:
Concomitantly with lattice disorder, there is a discrepancy between local and global scales in relaxor ferroelectrics, in that structural distortions occurring at the local scale are not reflected in the average global structure which remains cubic. There is an absence of direct implementation of the local symmetry in the modeling of relaxors, despite its considerable, but often unacknowledged, ability to encode local features. Central to the thesis is an explicit account for local gauge symmetry within the first-principles-derived effective Hamiltonian approach. The thesis thus aims to consid

Multi-axial polarization rotation tests on PMN-PT showed a gradual increase in the change in dielectric displacement due to ferroelectric switching as the electric field is applied at increasing angles to the initial polarization direction.

It has been the subject of many experimental and theoretical studies yet there are a number of unsolved questions preventing further miniaturisation and optimisation of this and other ferroelectric materials. Exotic ultra-dense domain morphologies, as an example, offer an exciting avenue for the development of novel nanoelectronics. In this work, large scale molecular dynamics is used to construct a strain-temperature phase diagram of the domain morphology of PbTiO3 ult
