Summary:Title screen
The assembly of colloidal semiconductive nanocrystals into highly ordered superlattices predicts novel structure?related properties by design. However, those structure–property relationships, such as charge transport depending on the structure or even directions of the superlattice, have remained unrevealed so far. Here, electric transport measurements and X?ray nanodiffraction are performed on self?assembled lead sulfide nanocrystal superlattices to investigate direction?dependent charge carrier transport in microscopic domains of these materials. By angular X?ray cross?correlation analysis, the structure and orientation of individual superlattices is determined, which are directly correlated with the electronic properties of the same microdomains. By that, strong evidence for the effect of superlattice crystallinity on the electric conductivity is found. Further, anisotropic charge transport in highly ordered monocrystalline domains is revealed, which is attributed to the dominant effect of shortest interparticle distance. This implies that transport anisotropy should be a general feature of weakly coupled nanocrystal superlattices.
