Work package number and title:

1. Invitation of the leading experts in the field of crystal growth to IPUL

Objectives:

1. University of Latvia has established a fruitful collaboration with the group “Floating-Zone, Czochralski” at the Institute for Crystal Growth (ICG) (Berlin, Germany). The group is very well technically and experimentally equipped; its leader Dr. H. Riemann is an internationally recognized high level specialist in experimental crystal growth. The group performs excellent experiments in silicon crystal growth, especially by Floating zone method and Si-Ge crystal growth by Czochralski method. The aim of the present WP is to coordinate the mutual activities, to discuss the experimental results obtained in ICG, to compare with results of numerical modeling obtained at Latvia University and to prepare common publications on the research proposed in the work plan of activity WP6. ICG plays an important role in German society for crystal growth and crystallography (DGKK). Therefore, the collaboration with ICG will stimulate contacts between the Institute of Physics in Latvia and other research groups in Germany in order to broaden the scientific collaboration and to find partners for participation in the EC networking programs in future.
2. University of Latvia has a fruitful collaboration with the group “Mathematical modeling of silicon single crystal industrial growth” at the Institute for Electrothermal Processes (ETP) at University of Hanover (Germany). The group has a leading position in world on the mentioned field and has a high level of software and computing capacities. Its leader Prof. A. Mühlbauer is an internationally recognized high level specialist in using of electrothermal methods, especially in crystal growth. The group performs excellent mathematical modeling work in large silicon crystal (up to 300 mm) industrial growth by Floating zone method and by Czochralski method. The aim of the present WP is to coordinate the mutual activities, to discuss and compare the results of numerical modeling obtained in ETP and at Latvia University and to prepare common publications on the research proposed in the work plan of activity WP6 ETP has many excellent co-operations with German industrial companies (e.g. Wacker Siltronic AG). Therefore, the collaboration with ETP will stipulate contacts between the Institute of Physics in Latvia and high-tech companies in Germany in order to broaden the applied scientific research and to find industrial and academic partners for participation in the EC networking programs in future.
3. Development of new engineering turbulence models needs experimental benchmark data. On the other hand, the benchmark experiments need specific knowledge on particular models and their implementation in applied simulation software (WP6): Aim of this package is to share expertise and to coordinate research activities in testing and implementation of advanced MHD turbulence models.
