Ripple rotation in epitaxial growth of MnAs(11¯00)
Abstract
Rippled states formation driven by kinetic instability is evidenced in the case of MnAs(11¯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. Golubović, Phys. Rev. EJPGCE81539-375510.1103/PhysRevE.76.041605 76, 041605 (2007)] for growth on rectangular symmetry surfaces, including Ehrlich-Schwoebel instability and effects related to vertical asymmetry.
