EPR spectroscopy of low-dimension structures produced in natural diamonds and synthetic diamond films by ion implantation (review)

We give a brief overview of the results of investigations that gave birth to new trends in radiospectroscopy, physics of interactions of atomic particles with condensed materials, and solid-state physics, especially, physics of superhard materials. The main factors that provided the basis for these trends are as follows.

High-energy ion implantation into solids plays a constructive role with respect to the solid matrix. A modified structure composed of matrix atoms and characterized by both short-range and long-range orders different from the initial one is formed as a result of this implantation. Low-dimension systems of a new class, whose properties are described in the present work, were produced in diamonds. A distinguishing feature of this new class of elements is that one-dimensional elements possesing their own spatial ordering of atoms constitute a volume superlattice composed of the same atoms in a three-dimensional crystalline matrix.
