Two-dimensional (2D) epitaxial materials including hexagonal boron nitride (hBN) are frequently employed as templates for self-assembled molecular films and nanostructures [1]. A quantitative structural characterization of the respective interfaces and adsorbate geometries however is largely missing. After reviewing some examples of molecular self-assembly on hBN, I will report on the geometric and electronic structure of a prototypical organic/insulator/metal interface, namely metalloporphines (Co-P, Zn-P) on hBN/Cu(111), investigated by combining X-ray photoelectron spectroscopy, X-ray...

Majorana states in atomic-scale magnet-superconductor hybrid systems have recently become of great interest because they can encode topological qubits and ultimately provide a new direction in topological quantum computation [1,2]. First, it will be demonstrated how well defined 1D atomic chains of magnetic adatoms on superconducting substrates with high spin-orbit coupling can be artificially fabricated using STM-based atom-manipulation techniques. Spin-polarized STM measurements [3] allow to reveal the presence of non-collinear spin textures, i.e. spin spiral ground states, stabilized by...
