Self-assembly is a promising approach for the fabrication of novel products based on
nano-structures. Prominent examples can be found for new electronic and light emitting devices. Many applications, however, not only require nano-structures of a specific size, shape and composition, but also demand for well-ordered arrangements of such nano-structures. Top-down ordering of these however is a time consuming and hence costly fabrication step. Recently, self-ordering has emerged as an alternative approach suitable for facilitating order during nano-structure formation. However, certain limitations regarding composition and other properties are inherent to this approach. In this talk we will present new concepts for the implementation of self-ordering into self-assembled growth on semiconductor surfaces. For this purpose synchrotron radiation based experiments have been performed using x-ray scattering as well as in-situ low-energy and photo emission electron microscopy.
