  The evolution of RHEED reflexes intensity during reconstructed transitions
characterizes (often implicitly) reconstructed surface state peculiarities. The
approaches of a correct RHEED data interpretation, aimed at obtaining
information about reconstructed transitions kinetics, are considered in the
present work. In particular, the nature of RHEED reflexes formation, depending
on such parameters as the average size of reconstructed domains and number of
such domains per area unit, is analyzed within the kinematic approximation of
the diffraction theory. This geometrical description is a convenient and
effective (productive) way of analyzing reconstructed transitions mechanisms
and parameters. The transformation of the functional dependence between the
measured values (RHEED reflexes intensity picture) and the degree of surface
coverage by reconstruction domains, at a change of these domains average size
and distribution density, is shown. This work provides the community with a
useful framework for such type of theoretical studies.
