Effects induced by nanocrystals interplay on carrier multiplication dynamics and absorption properties of low dimensional nano-systems: ab-initio results.
 
Nanocrystals (NCs) interplay  can be exploited to modify electronic and optical properties of low dimensional nano-systems. In this talk we will discuss two  aspects  that concern the NC-NC interaction: effects induced by NCs interplay on carrier multiplication (CM)  dynamics and effects induced by NC-NC interaction on the optical absorption properties of  nanostructured systems.  In the first part of the talk we will discuss CM dynamics in systems of isolated and interacting  silicon NCs (Si-NCs). Effects promoted by NCs interplay on CM dynamics (energy and charge transfer CM processes)  will be analysed and discussed in details. In the second part of the talk we will  consider systems of interacting germanium NCs (Ge-NCs). By using the densify functional perturbation theory, we will prove that NC-NC interaction can be exploited to modify absorption properties of Ge-NCs organised in a dense array.
