Bridging Atomistic to Continuum - Multiscale Investigation of Self-Assembling Magnetic Dots during Epitaxil Growth

Bridging Atomistic to Continuum - Multiscale Investigation of Self-Assembling Magnetic Dots during Epitaxil Growth

Objective

Spontaneous formation of nanostructures through kinetic and thermodynamic morphological instabilities at solid surfaces is increasingly recongnized as an attractive, low-cost alternative to top-down schemes for nanopatterning. We propose an integrated app roach to examine the self-assembly of magnetic nano dots by spanning the atomistic to the continuum scales. The work will involve ab initio calculations, as well as statictical mechanics, mesoscopic and continuum calculations of the evolution of nanostruct ural morphology, composition , and self-assembly during deposition and annealing. By parameter passing, each effort will feed into the other, as the information at the smaller scales will be employed at the larger scales scale caculations, enabling us to b ridge a wide range of length and time scales. The ultimate goal of the project is to develop an understanding of the important materials issue governing nanoscale self-assmbly, and to develop models that enable the first-principle design of novel super-hi gh density magnetic storage materials. The understanding of the fundamental phenomena accompanying dot formation gained through computational approaches and experimental validation will facilitate the development of processing methods that yield regular a rrays of magnetic nano dots for the next generation of magnetic storage materials.
