3. Electronic transport in nanocrystal arrays
Before discussing the use of nanocrystals in optoelectronic devices, it is necessary to explain the mechanisms of charge conduction in nanocrystal films.
3.1 Jump transport
A nanocrystal film is a disordered assembly of more or less monodisperse particles. The energy landscape used to model this assembly is therefore complex, corresponding as it does to a succession of variable-energy sites separated by tunnel barriers of varying lengths. Indeed, polydispersity introduces an energy dispersion in which large nanoparticles have the lowest energy and will therefore behave like traps. The spacing between nanoparticles is also poorly controlled, with at least the size of the ligands between particles, but this distance can be greater depending on the level of disorder....
