GENERALIZED EDSHAMMAR POLYHEDRA FOR THE DESCRIPTION OF A FAMILY OF SOLID-STATE STRUCTURES

A new class of space‐filling polyhedra does yeoman's service in the description of solid‐state structures. In this method the atoms of the minority component are considered as quasi‐isolated units located in the interstices of close‐packed polyhedra consisting of atoms of the majority component. These polyhedra are in a certain sense fragments of a body‐centered cubic packing of spheres. They are based on interpenetrating cubes. The sketch shows the polyhedron for three such cubes.
