Steuerung chaotischer Bewegungen Abschlussbericht

In an experimental system, a periodically driven bronze ribbon, we compare the feasibility of three methods for the control of instable periodic orbits in chaotic systems. We further investigate the influence of time-variing system-parameters.

SiC for sensors and high-temperature electronics

The paper presents an overview over recent developments in the SiC field. Within this field, two main streams are emerging: On the one hand, the commercial availability of bulk SiC crystals is likely to establish SiC as a new wafer technology which allows many devices to be fabricated in analogy to known Si ones. In this way, the high-temperature limit for the operation of sensors and electronic circuits can be significantly extended. Thin films of SiC, on the other hand, can be used as an add-on to the existing Si technology. Using such films, new possibilities emerge with regard to the fabrication of microsensors. Applications of thin-film SiC in optics, optoelectronics, and micromachining are demonstrated.

Oberflaechenmodifikation von Kunststoffen durch Ionenimplantation Abschlussbericht

For the first time ion beam techniques were investigated systematically with the aim industrial application. At first a vacuum chamber was constructed and built especially for the ion beam bombardment of polymers. This apparatus is also suitable for large area IBAD processing. Afterwards basic investigations showed the chemical changes induced by the ion beam in the polymers. Application oriented investigations were devoted to increasing the adhesion at the interface polymer/metal and to the barrier effects of the irradiations. In both cases considerable improvement was obtained in comparison with the non modified polymers. The improvement by ion beam techniques was compared with the one obtained with alternative modification methodes.
