NETWORKS OF SELF-ASSEMBLED Ge NANOWIRES IN Al2O3 GLASS: STRUCTURAL AND ELECTRICAL PROPERTIES

Regularly ordered semiconductor nano-objects embedded in glass matrices show very interesting properties and have many relevant applications. Therefore, the simple and efficient methods for production of such materials are of great importance. Here we present the conditions for controlled production of self-assembled Ge-nanowires in amorphous-glass Al2O3 matrix by a simple magnetron sputtering deposition. The wires are arranged in networks with controllable structural parameters. In that way is possible to control the length and cross-section of the wires between the neighboring nodes. Such structural properties strongly affect the electrical properties of the prepared materials. We show the dependence of electrical conductivity on the Ge nanowire network structure. The electrical conductivity show strong dependence on the Ge concentration and it is also affected by the preparation conditions.
