The mixed-halide MX solids [Pt(en)(2)] [Pt(en)2(X(y)X'(1-y))(2)] (ClO4
)(4) (X,X'=Cl, Br, or I; en=1,2-diaminoethane) - abbreviated PtX1-yX'y
- are realizations of nanoscale 1-D heterostructures in a well-charac
terized crystalline environment. Using resonance Raman spectroscopy, t
he complex interplay between quantum confinement, lattice mismatch eff
ects, charge transfer at heterojunctions, and electronic interaction l
engths across the junctions is explored for two CDW strength combinati
ons: the strong-/moderate-CDW case of PtCl1-xBrx the strong-/weak-CDW
case of PtCl1-xIx.
