Nanocrystal Superlattices

Abstract

Ordered arrays, or superlattices, of metallic, insulating, or semiconducting quantum dots, represent an exciting new class of materials. These superlattices are often referred to as artificial solids, in which the nanocrystals take the place of atoms in traditional solids, and the packing arrangement of the nanocrystals determines the unit cell parameters of the superstructure. In this review, we discuss various approaches toward assembling nanocrystal superlattices and we discuss their physical properties.
