Introduction

The main goal of the research is to optimise and to advance the IR converter to build a commercial product. Beside this work we are interested to understand more details of physical processes.

The work of our group takes place in co-operation with the people of the group pattern formation in gas discharge systems. The main interest of this group is to use the semiconductor-gas discharge structure as a non linear system. Many different structures can be observed with these systems. E.g. a homogeneous discharge can destabilise to a hexagon struture which develops to a stripe structure (behaviour is depending on changing of parameters). By getting more information of this behaviour the area of operations of the IR converter can be extended.
