Forschungsschwerpunkte

Compound semiconductors form a central topic at the Institute, in particular the problems of crystal growth. Other activities concern phosphors and optical data storage materials.
The Institute has developed strong ties to industry. As will be seen below most research projects are linked to co-operations with industrial partners. In these co-operations the Institute generally covers the more fundamental aspects of the corresponding problem. In this way the Institute forms part of the general concept of the Department of Materials Science and Engineering, which defines itself as a place of basic research as well as a partner to industry. A mayor industrial activity, the company SiCrystal AG, which is a supplier of silicon carbide semiconductor material, has developed out of the Institute VI.
A completely new activity in the field of wide-gap semiconductor growth was opened by starting a project on AlN. Aim of the project is the growth of bulk material, which, so far, is an unsolved problem in the field of crystal growth.
Also the activities of the Crystal Growth Laboratory (CGL), the working group of Prof. Dr. Georg Müller, have been successfully expanded in 2001. In its traditional fields of experimental crystal growth of Silicon and III-V semiconductors as well as of fluoride crystals the R&D merits of CGL contributed to the maintenance of the market position of its industrial partners. Their confidence in CGL is evident from the fact that the co-operations were continued on the same level despite of the economic contractions of the global semiconductor market. In the field of numerical modelling of crystal growth processes CGL has considerably extended its activities. This is underlined by the fact that in 2001 more than 20 license contracts about the software products developed at CGL have been placed with world leading companies and research institutions. Furthermore, CGL has spread its activities to new research areas in 2001. For example it started to research on oxide crystal growth and on bulk growth of nitrides as well as on fundamental metallurgical problems like the influence of convection on the microstructure formation in technical aluminium alloys during solidification.

Kooperationsbeziehungen

A number of scientific links have been developed in recent years with other Institutes of the Department as well as the Technical Faculty. Particularly strong connections exist to the Institute of Glass and Ceramics (including two common DFG-projects), to the Fraunhofer Institute for Integrated Circuits (Prof. Ryssel), the Institute of Fluid Mechanics (Prof. Durst) and the Institute of Applied Mathematics (Prof. Gräbner).
