Iron-rich lamellae in a semiconductor

There is often a pronounced symmetry when you look at the lattice of crystals: It doesn't matter where you look--the atoms are uniformly arranged in every direction. This behavior would also be expected of a crystal, which physicists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Warsaw and the Polish Academy of Sciences produced with a compound from an indium arsenide semiconductor spiked with iron. The material, however, did not adhere to perfect symmetry. The iron forme...
