Molecular electronics

  • Frontier molecular orbitals of MnPc

    Miniaturization of the electronic circuits used in digital devices lies at the heart of current technological revolution. A promising strategy is to employ molecules as efficient building blocks, replacing transistors, resistors or contacts by objects as small as few atoms. This effort lead to the emergence of a new interdisciplinary research field of molecular electronics. We employ a combination of the density-functional theory (DFT) with Green function-based techniques to study the transport properties of molecular devices.

Correlated materials with strong spin-orbit interactions

  • Generalized bandstructure of BaOsO3

    We use the combination of ab-initio (LDA) methods and dynamical mean-field theory (DMFT) to study materials with strong effect of spin-orbit coupling on their electronic and magnetic properties. The focus lies on transition-metal oxides with heavy ions such as iridium and osmium. We use the continuous-time quantum Monte-Carlo method in the strong-coupling limit (CT-HYB) to solve the underlying impurity problem.
