When displacement reactions are associated with electroless deposition of silver, exotic coaxially-organized heterostructures, characterized by hybrid chemical compositions, are generated [17, 125]. The heterostructures present a concentric topology of the various metals, a sort of Matrioshka arrangement known as nanorattles as defined by the same authors [17], Different shape and material configurations have been reported in literature, for instance onto spherical AuAg alloy core NCs, Ag could be deposited by chemical reduction promoted by ascorbic acid at high temperatures and water environment, afterwards, a redox displacement HAuCU-promoted altered the silver shell composition... 

Unlike the heterostructures whose periodic structure must be accurately controlled, the formation of nanocomposite structure is self-organized based upon thermodynamically driven spinodal phase segregation [118-121]. For the CVD...

The time has come to make a quantum leap, both figuratively and literally. Short-term solutions may exploit organic semiconductors [31-33] and semiconductor quantum heterostructures [34, 35]. A long-term solution will be provided by molecular electronics [36-40] in which single molecules are employed as integrated circuits [41, 42].

Fabrication or InP/InAs/InP core-multishell heterostructure nanowire arrays shown in Fig. 24 has been achieved by selective area metal-organic vapour phase epitaxy.1 These core-multishell nanowires were designed to accommodate a strained InAs quantum well layer in a higher band gap InP nanowire. Precise control over the nanowire growth direction and the heterojunction formation enabled the successful fabrication of the nanostructure in which all the three layers were epitaxially grown without the assistance of a catalyst.

Now that these organic/inorganic heterostructure semiconductors can be made, we can use them to increase the range of potentially harmful materials that can be detected in time to prevent a dangerous incident. I ll briefly discuss the applications of these semiconductor materials to national security needs, including devices such as infrared (IR) detectors and sources, gamma-ray detectors, and chemical/biological sensors.
