Iron-Rich Lamellae in the Semiconductor
Press Release of 07.12.2018
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 was also to be expected by a crystal, which physicists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Warsaw and the Polish Academy of Sciences produced, using a special process: a compound from an indium arsenide semiconductor, spiked with some iron. The material, however, did not adhere to perfect symmetry. The iron formed two-dimensional, lamellar-shaped structures in the crystal that lent the material a striking property: it became magnetic. In the long term, the result could be vital in understanding superconductors.
