Additional Info
Chair of Semiconductor Nanostructures and Quantum Systems: focus on understanding, manipulating and exploiting electronic, spin and photonic quantum phenomena in semiconductors and nanostructured electronic and photonic materials. Major research interests include: optical, electronic and spintronic properties of semiconductor quantum dots and wires fabricated from Aimonides, group-IV materials (Si, SiGe, C) and II-VI semiconductors and oxides (CdSe, ZnO). Another major arm of our research concerns quantum optical studies of dielectric and metallic nano-photonic materials and the application of such systems for applications in quantum information processing, metrology and sensing.

2D semiconductors-based synthetic superlattices for quantum simulation
The van der Waals stacking of different 2D crystals on top of each other has underpinned a recent series of remarkable discoveries including the demonstration of unconventional superconductivity in twisted bilayer graphene. In twisted bilayers of 2D semiconductors, the moiré superlattice pattern induced by the twist angle can localize excitons or electrons, yielding a periodic array of quantum-confined particles. Thanks to the strong many-body interactions inherent to 2D materials, such arrays have allowed the simulation of quantum many-body systems such as in correlated insulators, magnetism, and generalized Wigner crystals. [1]However, this approach to generating superlattices is subject to strict limitations on superlattice geometry from materials properties, and by extrinsic inhomogeneities introduced in the stacking process. [1]In this project, we pioneer a scalable and deterministic top-down approach to superimpose synthetic superlattices on an underlying bilayer system. Using this versatile technique, we study correlated phases, especially in configurations that cannot occur in natural matter.

Exciton Physics of 2D layered Gallium Selenide (GaSe)
In contrast to the widely studied graphene and transition metal dichalcogenide (TMD) family of 2D layered semiconductors (MoS2, MoSe2, WS2, WSe2), the group-III monochalcogenides (III-MCs) MIIIX (MIII∈{In,Ga} and X∈{S,Se,Te}) are much less investigated but show remarkable physical properties and technological applications [1]. In particular, the bandgap of III-MCs can be tuned over the infrared to the ultra-violet spectral range as a function of layer thickness and the switch to direct gap as the number of layers increases from a single to a few (typically 3-7) layers is reported [2]. In our group, we study the intriguing chemical, electronic, optical and vibrionic properties of III-MCs materials. The aim of this project is to study the optical emission of mechanically exfoliated 2D Gallium Selenide (GaSe) obtained by standard industrial growth methods and compare it with films newly synthesized in our lab by molecular beam epitaxy (MBE). You will learn how to create 2D devices by exfoliation and subsequent encapsulation, which is the process of covering a 2D materials of interest with another insulating 2D material for environmental protection. You will then develop a solid knowledge of fundamental spectroscopy by analyzing the excitonic lines from photoluminescence spectra in a cutting- edge laboratory. Additionally, you will correlate the results with differential reflectivity measurements and Raman spectroscopy in order to evaluate the absorption and band structure and the crystallographic structure, respectively. While working on the project, you will learn about how to create and investigate devices with a new material, earn a deep understanding of recombination processes in 2D materials and develop data analysis and programming skills. We are seeking highly motivated, hardworking students with an inclination for technical and optical lab work. Some experience with optical spectroscopy, 2D materials, cleanroom fabrication, scripting (Python) will be beneficial but not essential.
