Ripple Rotation In Epitaxial Growth Of Mnas(1(1)Over-Bar00)

Rippled states formation driven by kinetic instability is evidenced in the case of MnAs(1 (1) over bar 00) hetero- and homoepitaxial growth in a narrow multistable range of growth parameters. The evolution of the surface morphology in this range, comprising slope selection and ripple rotation, maps the kinetic phase diagram recently predicted [A. Levandovsky and L. Golubovic, Phys. Rev. E 76, 041605 (2007)] for growth on rectangular symmetry surfaces, including Ehrlich-Schwoebel instability and effects related to vertical asymmetry.
