Welcome to the AG Wurstbauer
Tailored quantum nanosystems: electronics – photophysics – interactions – collective behavior
We experimentally focus on exploration of the light matter interaction, charge of functional sites on the atomistic level and at interfacial processes as well as on emergent phenomena in novel two-dimensional quantum materials such as transition metal dichalcogenides, graphene, hexagonal boron nitride, 2D polar metals and their hetero- and hybrid structures. The aim is to gain a fundamental understanding of the physical properties of those systems, and to learn – in a next step – to control and tailor them on purpose with the vision to achieve novel functionalities and at the same time to look for potential applications in an interdisciplinary context. These low-dimensional systems are therefore integrated in nano- and microscale circuitries, as well as in proof-of-concept and prototypical devices to explore their potential for opto-/electronic applications and to serve as test-bed structures towards (topological) quantum technologies.
For all above research directions, we thank Deutsche Forschungsgemeinschaft (DFG) for funding in several projects. In particular, we are grateful for the support of the excellence cluster Nanosystems Initiative Munich (NIM) and the excellence initiative e-conversion.

WE-Heraeus-Seminar - 2D Materials and Hybrids: Hybrid Quasiparticles in Quantum Materials
Quasiparticles and their mutual interactions form the basis for quantum technologies and integrated opto-/electronic circuits with embedded novel functionalities. It is therefore important to understand the underlaying correlations including coherence properties and their dynamics on a very fundamental level. Material platforms hosting such quasiparticles and potentially allowing the implementation of integrated circuitries with intelligent or quantum functionalities are two dimensional (2D) materials and their hybrids formed from e.g. coupling with plasmonic structures. Two-dimensional materials exhibit a rich set of quasiparticle excitations, together with exciting spin and valley properties and topological non-trivial materials. 2D materials such as the intensively studied class of transition metal dichalcogenides (TMDCs), tetradymites, and further 2D materials with distinct topological properties have emerged as a platform to realize, understand and tailor quantum hybrid structures. They can be combined with arbitrary substrates, be twisted, and be assembled into heterostructures. Those 2D materials can be interfaced with plasmonic films and nanostructures to fundamentally study weak and strong interactions, as well as energy and information transfer between the different quasiparticles and for the realization of hybrid quasiparticles that can be integrated in functional units. The aim of the seminar is bringing together a group of excellent internationally well-established researchers working on 2D materials, hybrids and their quasiparticles from various points of views using different characterization tools, materials, or theoretical methods to foster synergy. Young researchers at the PhD or PostDoc levels will be encouraged to actively participate with poster presentations, at a panel discussion and a synergy workshop session.
The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
