Effects of Non-Stoichiometry on the Lattice Constant of Semiconductor Nanocrystals: CdSe and GaAs
We have examined the role of different terminating geometries in modifying the equilibrium lattice constant of semiconductor nanocrystals. In the case of binary semiconductors, the different criteria adopted for terminating the nanocluster lead to different surface stoichiometry. As
a consequence similar sized nanocrystals are found to have different equilibrium lattice constants.
