posted on 2013-01-31, 16:05 authored by Sabrina Blackwell, Roger Smith, Steven KennySteven Kenny, Louis J. Vernon, Michael WallsMichael WallsResults are presented for modeling the growth of TiO2 on the rutile (110) surface. We illustrate
how long time scale dynamics techniques can be used to model thin film growth at realistic growth
rates. The system evolution between deposition events is achieved through an on-the-fly Kinetic
Monte Carlo method, which finds diffusion pathways and barriers without prior knowledge of
transitions. We examine effects of various experimental parameters, such as substrate bias, plasma
density, and stoichiometry of the deposited species. Growth of TiO2 via three deposition methods
has been investigated: evaporation (thermal and electron beam), ion-beam assist, and reactive
magnetron sputtering. We conclude that the evaporation process produces a void filled, incomplete
structure even with the low-energy ion-beam assist, but that the sputtering process produces
crystalline growth. The energy of the deposition method plays an important role in the film quality.
