Surface stress anisotropy of Ge(001).
By analyzing the equilibrium shape of vacancy islands on the Ge(001) surface we have determined the surface stress anisotropy, i.e., the difference between the compressive stress component along the substrate dimer rows and the tensile stress component perpendicular to the substrate dimer rows. In order to extract the surface stress anisotropy we have used a model recently put forward by Li et ...
متن کاملAirborne Measurements of Surface Anisotropy
Surface spectral bidirectional reflectance is a major parameter of interest to the biospheric sciences, remote sensing, and global change communities. For example, the pronounced reflectance peak at the back scattering range of vegetated surfaces, known as the “hot spot” or “opposition surge” (cf. Hapke 1993), is found to be closely related to the state of several biophysical and physical param...

متن کاملSurface Morphology and Magnetic Anisotropy
Understanding the correlation between film structure and its ferromagnetic properties is very important for applications. Despite significant lattice mismatch epitaxial (001) fcc Ni films can be grown on MgO substrates using sputtering or molecular beam epitaxy (MBE). For both types of films it is observed that the average magnetization switching field is very similar but its azimuthal dependen...
متن کاملSurface structure and anisotropy of Eden clusters
The simple Eden model is simulated with clusters which are orders of magnitude larger than those of some previous work. The 'surface' (perimeter) is slightly anisotropic and feels the underlying structure of the square lattice even for 17 million cluster sites. The width of the surface layer increases with increasing cluster mass, with an effective exponent presumably larger than 1/4 for averag...
