Henriette Elisabeth Lund

During her PhD studies, Henriette Elisabeth Lund investigated the electronic properties of different quantum materials. The studied materials (Sb2Te3, Nb-doped Bi2Se3, NdTe3, and Ca2RuO4) are of interest in connection with future technology such as quantum computation and spintronics. Henriette Elisabeth Lund performed an experimental investigation of the electronic structure of the mentioned materials. Examples of important findings from these experiments is that Nb-doped Bi2Se3 is an inhomogeneous material and that NdTe3 possesses an electronic structure more complicated compared to previous findings. It was furthermore found that passing a current through Ca2RuO4 leads to an insulator to metal phase transition, confirming previous studies.  

The research findings contribute to the understanding of the fundamental physical properties of the mentioned materials, which is important if they are to be technologically exploited.

The PhD study was completed at Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
