step structure
In the intermediate spectral region, a step structure is formed as a result of "elimination" of the contribution from the reciprocal lattice vector with a preset magnitude to the coherent component of the process.
      
Atomically resolved STM images reveal (7 × 7) terrace ordering and triple step structure.
      
The corresponding potentialvxc,scrresp has a clear step structure and is constant within the atomic shells and changes rapidly at the atomic shell boundaries.
      
A cluster model represents the step structure and the oxygen impurity is deposited in this cluster above the dimer rows.
      
The current-induced step structure in the phase transition from the superconducting to the normal conducting state of whiskers of tin shows hysteretic behaviour.
      
For vicinal SrTiO3(001) surfaces the particular annealing sequence and miscut angle sensitively determines the resulting step structure and thus the microscopic surface morphology.
      
For the first time we were able to achieve high-resolution images showing simultaneously a clear domain wall contrast and the underlying atomic step structure.
      
Step structure and dynamics and adsorbate-induced reconstruction of stepped surfaces are useful features for investigating fundamental surface phenomena and their practical consequences.
      
A step structure of approximately 30?nm in width was directly observed, which was formed during the polarization reversal process.
      
The presence of the step structure reveals that the forward domain-growth mechanism is the dominant domain-switching process in our PZT thin films.
      
Elastic interband scattering strongly depends on details of the backfolding of the bands by the periodic step structure.
      
An atomically flat terrace-step structure was consistently observed on Rh(111) surfaces prepared by the flame-annealing-quenching method.
      
The increase in the complex permittivity during switching is calculated from a two-dimensional model of residual nuclei, assuming that domain walls possess a pyramidal step structure.
      
It is shown that the real part of the permittivity during switching is very sensitive to the presence of steps on moving domain walls and that there is an indication that in BaTiO3 such step structure actually exists.
      
Further complications arise from the existence of a conductive step structure along the coastline at the Moho boundary and a 'graben' in the Palk Strait.
      
I propose such a model with a form that reflectsa two-step structure.
      
A multi-step structure, consisting of three phases, is developed.
      
One final factor in coverage dependence of diffusivity is considered, namely, the possible effects of coverage on the surface step structure.
      
Scanning tunnelling microscope investigations of the sample surface revealed steep step structure with 10×10 nm2 size crystallites and 5 to 100 nm high terraces.
