Coarsening of Unstable Surface Features During Fe(001) Homoepitaxy |

| Abstract: |
The evolution of the surface profile during homoepitaxial growth of Fe(001) is studied by scanning tunnelling microscopy and reflection high energy electron diffraction. The observed morphology exhibits a non-self affine collection of mound-like features that maintain their shape but coarsen as growth proceeds. The characteristic feature separation L is set in the submonolayer regime and increases with thickness, t, as L ~ t 0.16 {plus or minus} 0.04. During the coarsening phase, the mounds are characterized by a magic slope and a lack of reflection symmetry. These observations are shown to be described by a continuum growth equation without capillarity. |
