Faceted QDs with a truncated octahedral shape were prepared and deposited in a solvent on a pyramidal microhole array prepared on a Si (100) substrate. During the deposition, facets of neighboring QDs arranged in contact with each other in the aligned microholes. The three-dimensional crystal orientation alignment was confirmed by X-ray pole figure mapping. Such QD superlattice film with aligned crystal orientation can contribute to the realization of a high energy-conversion efficiency of semiconductor solar cells.}, title = {Superlattice formation of faceted PbS quantum dots with three-dimensionally aligned crystal orientation}, volume = {11}, year = {2018} }
