Formation of long-range ordered quantum dots arrays in amorphous matrix by ion beam irradiation
We demonstrate the production of a well ordered three-dimensional array of Ge quantum dots in amorphous silica matrix. The ordering is achieved by ion beam irradiation and annealing of a multilayer film. Structural analysis shows that quantum dots nucleate along the direction of the ion beam used for irradiation, while the mutual distance of quantum are determined by diffusion properties of the multilayer material rather than distances between traces of ions that are used for irradiation.
