(Phys.org)—Scientists at the University of Texas at Austin and Cornell University have fabricated the first ordered arrays of silicon nanocrystals reported to date. Brian A. Korgel and colleagues developed a new chemical method to generate tiny silicon crystals—or quantum dots—with precisely controlled size and then relied on nature to organize them into regular structures. The new self-assembled arrays, presented in the journal ChemPhysChem, could help researchers exploit the promising light-emitting properties of one of the most commercially important semiconductors.
