      abstract     = {Superlattices of quantum-confined perovskite nanocrystals
                      (5–6 nm) present an interesting example of colloidal
                      crystals because of the interplay between nanoscopic
                      parameters (nanocrystal sizes, shapes, and colloidal
                      softness) and the microscopic shapes of their assemblies.
                      These superlattices are reported as rectangular or rhombic,
                      with little discussion of the outcomes of self-assembly
                      experiments which are worthwhile to study given the rising
                      interest in the optical properties of these nanomaterials.
                      It is observed that various super-lattice shapes are
                      produced in a single solvent evaporation experiment from a
                      nanocrystal dispersion drop-casted onto a tilted substrate.
                      The observed shapes are categorized as rhombi, rectangles,
                      and hollow frames (including hollow rectangular frames,
                      nested structures, and interconnected fragments).The
                      influence of self-assembly conditions is studied by optical
                      microscopy, and the nanocrystal circularity, aspect ratio,
                      and size are quantified by transmission electron microscopy
                      with additional insights into the superlattice structure
                      provided by X-ray nano-diffraction. The results suggest that
                      rhombic shapes arise from a subpopulation of nanocrystals
                      with broader size and shape dispersions, whereas more
                      uniform nanocrystals form rectangular structures(either
                      solid or hollow). The solvent evaporation dynamics and
                      diffusion of the drying liquid contribute to forming more
                      complex shapes, such as nested frames and cracked and
                      multidomain superlattices.},
