One of the main problems of a nanomaterial is its structure, i.e. the disposal of atoms in small nanometric clusters that are free or not of interaction with other clusters in a bulk solid or in a thin film. Atomic scale modelling of various nano-clusters has been performed taking into account the crystallochemical parameters for every type of material: silicon nanowires, carbon nanotubes configurations, chalcogenide glass clusters. The modelling gives the possibility to select the physically realistic configurations, to be prepared and, thereafter, to be applied in nano-devices. Examples of nano-devices suggested as applications of the nanometric structures are given.
