This project employs cryogenic scanning tunneling microscopy (STM) to create atom-based quantum structures on semiconductor surfaces and explore their electronic properties by scanning tunneling spectroscopy. By assembling ionized adatoms with atomic…

Microcavity exciton-polaritons (polaritons) are light-matter quasi-particles arising from the strong coupling of photons and quantum well excitons in a semiconductor microcavity. Polaritons are composite bosons with µm-sized thermal de-Broglie wavelengths…

This project aims at the realization of hybrid quantum systems based on the coupling of single electrons and single phonons in the form of acoustic waves in tailored nanostructures. Our focus is the study of the electron-phonon interaction in systems…

The key objective of this project is the development of integrated terahertz quantum-cascade lasers for high-resolution spectroscopy and future space applications at 3.5 THz and 4.7 THz. These two frequencies are very important for the detection of the OH…

This project aims to provide new experimental insights into the formation and impact of point defects in Ga2O3. We approach this challenge by cross-linking different experimental characterization techniques, such as micro-Raman spectroscopy and…

Aharonov-Bohm spectroscopy is a powerful tool to study the quantum statistics of quasi particles in the integer and fractional quantum Hall regimes. Related major activities are in particular driven by the search for non-abelian states which could pave…
