Air-stable PbSe/PbS and PbSe/Pb[Se.sub.x][S.sub.1-x] core-shell nanocrystal quantum dots and their applications
Article Abstract:
The optical properties and functionality of air-stable PbSe/PbS core-shell and PbSe/Pb[Se.sub.x][S.sub.1-x] core-alloyed shell nanocrystal quantum dots (NQDs) are characterized. The results have revealed a relatively large gain parameter. The conductivity properties of PbSe NQD self-assembled solids have showed an Ohmic behavior at the measured voltages, which is governed by a variable-range-hopping charge transport mechanism.

Mixed quantum/classical molecular dynamics simulations of the hydrated dielectron: The role of exchange in condensed-phase structure, dynamics and spectroscopy
Article Abstract:
The mixed quantum/classical molecular (QM/CM) dynamics simulations of two excess electrons, called bipolarons, solvated by bulk liquid water, are performed at the Born-Oppenheimer approximation level. Analysis explored the role of quantum mechanical exchange in the properties of solvated quantum objects, and importance of spin statistic in determining the structure and dynamics of such objects.

Spectroscopic properties of molecular-wire/semiconductor nanocrystalline superstructures
Article Abstract:
The optical properties of molecular/ semiconductor noncrystalline (NCs) superstructures were examined. The superstructures study shows typical quantum size effect properties of the NCs and additional collective properties not encountered by the individual NCs.
