Summary on Grant Application Form |
|
X-ray scattering measurements will be made of the structure of thin films and superlattices for both metals and semiconductors in collaboration particularly with the LaMBE facility and MOVPE antimonide facility in Oxford Physics. Detailed studies of the structure of thin lattice mismatched films will provide information about when islands are grown and the perfection of the film as a function of film thickness. Studies of superlattices will enable us to distinguish between conformal and non-conformal roughness of the interfaces and in systems in which the layers have a large mismatch explore the structure of the quantum dots which may be found in one of the materials. These results will lead to a better understanding of the growth of thin films and hence to better control of the materials grown. We hope to extend these studies to ferroelectric films in the future. The phase transitions of bulk ferroelectrics will be studied particularly for systems with competing interactions. Measurements of the disordered low temperature structure for systems, like Ca doped SrTiO3, will enable us to understand the non-ergodic behaviour.
