Πηγή:ScienceDaily wrote:ScienceDaily (Feb. 10, 2010) — Just as the heartbeats of today's electronic devices depend on the ability to switch the flow of electricity in semiconductors on and off with lightning speed, the viability of the "spintronic" devices of the future -- technologies that manipulate both the flow and magnetic "spin" of electrons -- will require similarly precise control over semiconductor magnetism.

... in results published Feb. 5 in the journal Science, a Princeton-led team of scientists has observed electrons in a semiconductor on the brink of the metal-insulator transition for the first time. Caught in the act, the electrons formed complex patterns resembling those seen in turbulent fluids, confirming some long-held predictions and providing new insights into how semiconductors can be turned into magnets. The work also could lead to the production of smaller and more energy-efficient computers.

αλλά... δεν μπορούσα ν'αντισταθώ.
Γενικά κατάλαβα ότι η "μικροδομή" του υλικού παίζει πολύ σημαντικό ρόλο στις φυσικές του ιδιότητες. Τώρα το θέμα που ανέφερες ούτε εγώ το έπιασα...
