Optical detection of free carriers in 2D materials

This project will focus on the optical detection of free carriers in 2D materials. The insights gained will enable the extraction of carrier numbers from the absorption and emission spectra of 2D crystals subjected to high magnetic fields. Understanding the optical responses of low-dimensional, many-body systems is crucial for advancing future optoelectronic devices in quantum technologies. Developing a theoretical framework for the optical properties of correlated electrons in 2D crystals will clarify the nature of the many-electron ground state in systems such as transition metal dichalcogenides, bilayer graphene-based field-effect transistors, and gated quantum dots. This progress opens pathways for controlling light-matter interactions through carrier density, exploring quantum sensing of single photons via trions in gated quantum dots, and designing novel optoelectronic devices for quantum computing applications.
