Si1−xGexY Alloy Nanocluster Materials Chemical Vapor Deposition of Si2H6Ge2H6 Mixtures in Zeolite Y

Abstract

ABSTRACTSi1−xGexY alloy nanocluster materials are synthesized by the chemical vapour deposition of Si2H6/Ge2H6 mixtures within the diamond lattice of 13Å supercages in acid zeolite Y. A multianalytical approach to the study of these Si1−xGexY nanomaterials over the full compositional range 0<x<1 provides information concerning the mode of formation, geometric and electronic structures, trends in the optical properties of the encapsulated alloy nanoclusters.
