text: An appropriate way of realizing property nanoengineering in complex quaternary
chalcogenide nanocrystals is presented for Cu2Cd xSnSey(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.
