Transition metal oxides harbor a plethora of emergent electronic phases unaccounted for in conventional band theory. The reason hereto is the strong localization of electrons in the conduction bands with d-orbital character, inducing electron-electro

Die Dissertation beschäftigt sich mit der Analyse von oxidischen Nanostrukturen. Die Grundlage der Bauelemente stellt dabei die LaAlO3/SrTiO3-Heterostruktur dar. Hierbei entsteht an der Grenzfläche beider Übergangsmetalloxide ein quasi zweidimensi
Manifold research has been done to understand the detailed mechanisms behind the performance instabilities of ferroelectric capacitors based on hafnia. The wake-up together with the imprint might be the most controversially discussed phenomena so far

Hafnium oxide is widely used for resistive switching devices, and recently it has been discovered that ferroelectricity can be established in (un-)doped hafnium oxide as well. Previous studies showed that both switching mechanisms are influenced by o

The development of the Honeycomb Kitaev Model by A. Kitaev in 2006 [1] has excited the solid state physics community. A. Kitaev showed that an ideal honeycomb lattice with spin-1/2 moments sitting at each corner can show the highly desired quantum sp

Hexagonal iridates like Na2IrO3, alpha-Li2IrO3 or beta-Li2IrO3 are promising candidates for the realization of the Kitaev exchange interaction, which describes an anisotropic and bonding dependent interaction that can lead to novel types of spin liqu

In quantum materials, valence electrons experience strong mutual interactions, which can lead to the spontaneous emergence of multifarious collective electronic and magnetic phases. These include Mott insulating phases, superconductivity, antiferroma

This thesis covers different problems that arise due to crystal and pseudospin anisotropy present in 3d and 5d transition metal oxides. We demonstrate that the methods of computational quantum chemistry can be fruitfully used for quantitative studies

In der vorliegenden Arbeit werden die strukturellen und magnetischen Eigenschaften verschiedener 3d-Übergangsmetalloxidketten (TMO-Ketten) auf Ir(001) und Pt(001) untersucht. Diese weisen eine (3 × 1) Struktur mit periodisch angeordneten Ketten auf
