Microfacet notation

A kinked surface, like fee (10,8,7), can also be approximately expressed in this fomi the step plane (h k / ) is a stepped surface itself, and thus has higher Miller indices than tlie terrace plane. However, the step notation does not exactly tell us the relative location of adjacent steps, and it is not entirely clear how the terrace width M should be counted. A more complete microfacet notation is available to describe kinked surfaces generally [5]. 

It is obvious from Figure 4.16 that giving just the Miller indices provides no good imagination about the microscopic characteristics of the surface. Therefore, more self-explaining notations were introduced. These are the so-called step notation on the one hand and the microfacet notation on the other. Both use - additional to the orientation of the terraces - the orientation of the microfacet making up the... 

This was introduced by Van Hove and Somorjai and named microfacet notation [4], It concentrates on cubic crystals and uses that... 

As obvious, the possibilities for the arrangement and orientation of surface steps and terraces are numerous. Table 4.3 provide some examples for kinkless fee surfaces with both the step and microfacet notation given. A more stringent introduction to the notation of surface steps has been published recently [5].
