It describes how to make quantum dots, precursors, conditions, and the resulting properties, covering the preparation of II-VI, III-V, and IV-VI semiconductor nanomaterials and other chalcogenides and pnictide
nanomaterials; the synthesis of core/shell quantum dots; ligand chemistry; and the use of single-source precursors in nanoparticle synthesis.
Put differently, for the fact that spin is relevant in Fe pnictide
superconductors, they are basically itinerant magnetism suggesting that the Mott - Hubbard physics may be irrelevant in physics of Fe pnictide
The spark plasma sintering system will be used to consolidate nanosized powders (including but not limited to chalcogenides, pnictides
, intermetallic, and metal oxide samples) into nanocomposite disks with reasonable mechanical strength and good intergrain connectivity.

Studies of the internal structure of cuprates and pnictides
led researchers to the idea that a superconductor is a hamburger, in which the electric current flows through the 'meat', while the 'buns' act as a supplier of electrons (Collins, 2009).
Common high-temperature superconducting materials include bismuth strontium calcium copper oxide (BSCCO), lanthium barium copper oxide, yttrium barium copper oxide (YBCO), iron pnictides
, and mercury barium calcium copper oxide.
Our finding of a quantum critical point in iron pnictides
opens the door for new avenues of research into this important class of materials," said University of Tennessee/ORNL physicist Pengcheng Dai, a neutron scattering specialist.
