Anders B. Blichfeld

During his PhD studies, MSc. Anders B. Blichfeld has researched various thermoelectric materials by examining their crystal structures and related them to the physical properties. Thermoelectric materials can convert waste heat into electrical energy without the use of moving parts and no maintenance. By sending an electrical current through thermoelectric materials the same physical process can be used for refrigeration.
Anders B. Blichfeld have examined the two thermoelectric materials zinc antimonides and copper chalcogonides which are two of the best materials because og their cheap elements and high performances. The structure of copper selenide has so far been unknown at low temperature, but has been solved as part of the research project. By varying the composition of zinc antimonides one can form various crystal structures, and through the synthesis method, various structures obtained for the same composition. The research results contribute to the understanding of the complex material system with new structures, and related physical properties. A new method to study materials made of thin films has been developed, for measuring their structures and properties simultaneously, for amorphous as well as crystalline thin films.

The PhD degree was completed at the Department of Chemistry, Science and Technology, Aarhus University.
