abstract = {An appropriate way of realizing property nanoengineering in
complex quaternary chalcogenide nanocrystals is presented
for Cu2CdxSnSey(CCTSe) polypods. The pivotal role of the
polarity in determining morphology, growth, and the
polytypic branching mechanism is demonstrated. Polarity is
considered to be responsible for the formation of an initial
seed that takes the form of a tetrahedron with four
cation-polar facets. Size and shape confinement of the
intermediate pentatetrahedral seed is also attributed to
polarity, as their external facets are anion-polar. The
final polypod extensions also branch out as a result of a
cation-polarity-driven mechanism. Aberration-corrected
scanning transmission electron microscopy is used to
identify stannite cation ordering, while ab initio studies
are used to show the influence of cation
ordering/distortion, stoichiometry, and polytypic structural
change on the electronic band structure.},
