Assembly of PbTe/Pb-based nanocomposite and photoelectric property.

PbTe/Pb-based nanocomposite was assembled by combining the regular PbTe/Pb nanostructure and the ZnxMn1-xS nanoparticles; the photoelectric property of the nanocomposite was measured in situ. The results showed that the through current of the nanocomposite had an obvious increase compared to that of the individual PbTe/Pb nanomaterial under the same irradiation conditions. The improvement of photoelectric performance would be attributed to the synergistic effect brought by the incident light and exciting light of the ZnxMn1-xS nanoparticles.

PbTe/Pb quasi-one-dimensional nanostructure material: controllable array synthesis and side branch formation by electrochemical deposition.

A periodic PbTe/Pb nanostructure material with quasi-one dimension has been electrodeposited onto a SiO(2)/Si substrate by fabricating an ultra-thin electrolyte layer. The emergence of side branches at the edge of the nanowire array results from the non-uniform electric field distribution and the polycrystalline structure of the nanowires. The measurement of the electrical characteristics indicates that the crystal boundaries and defects in the nanowire could influence the change of resistance in the branch parts.

Potential-induced copper periodic micro-/nanostructures by electrodeposition on silicon substrate.

We demonstrate the fabrication of large scale nano- and micropatterned copper periodic structures on a silicon substrate without imposed templates. In the electrodeposition process, we employ a periodic variation voltage in an ultrathin layer of concentrated CuSO(4) electrolyte. The pattern can be controlled by varying the frequency of the applied potential.
