Theoretical studies of nano self-assembly
Greaney, Peter Alexander.

Theoretical studies of nano self-assembly [electronic resource] - 74 p.

Chair: Daryl C. Chrzan.

Thesis (Ph.D.)--University of California, Berkeley, 2003.

The role of surface strain in the growth of self-assembling nanostructures is investigated theoretically. The magnitude of the strain at the surface of a film generated by a buried array of misfit dislocations is calculated. It is demonstrated that such a film provides a suitable substrate for wavelength controlled spinodal decomposition of a second film grown on top of it. The role of homogeneous substrate strain is discussed in the context of how it affects diffusion processes and how these, in turn, impact island growth. An existing mean-field analysis of island growth is extended to include anisotropic diffusion. The results of the mean field calculations are compared with kinetic Monte Carlo simulations. It is found that anisotropy in adatom hopping reduces the density of stable islands. It is also found that although the shape of island size distribution is sensitive to island relaxation processes; it is not discernibly affected by hopping anisotropy with ratios DxxDyy up to 16. A diffusion mechanism involving the recently discovered surface crowdion is hypothesised and the implications of this mechanism on island growth are studied through KMC simulations.
