  3. Nucleation and Growth of Order in Cu(3)Au (111) Films

    Bonham, Scott WilliamUniversity of Illinois at Urbana-Champaign2015

    During epitaxial growth of (111) face-centered cubic crystal films, such as disordered $\rm Cu\sb3Au,$ there are two possible ways that successive layers can be laid down, leading to two types of stacking domains. However, a small vicinal miscut $(0.5\sp\circ {-}1\sp\circ )$ of the crystal surface …
