Semiconductors are an essential part of most modern day technologies, and an ever-ongoing effort towards optimizing the performance of these has taken place over the last hundred years. During her studies, Ellen researched how the level of control over the structures of semiconductors can be further improved through exploiting advanced solidification methods. When a material solidifies from a melt the constituents of the melt will preferable either be incorporated into the solidifying material or stay in the melt. By carefully planned experiments this can be exploited to obtain materials containing gradients in their properties. Utilizing this mechanism Ellen synthesized and characterized semiconductors of highly specialized properties. The research findings from Ellen’s thesis contribute to optimize semiconductors for specialized applications.

The PhD research was conducted at the Institute of Chemistry, Science and Technology, Aarhus University.
