B02 — Nanoscale optical imaging and spectroscopy of mol2Dmat heterostructures
Principal Investigator: Dr. Sebastian Heeg
Located at: Humboldt-Universität zu Berlin
Project B02 investigates charge transfer in mol2Dmat heterostructures with high spatial resolution using tip-enhanced Raman and photoluminescence spectroscopy. It bridges the gap between nanoscale and microscale techniques to study how defects, strain, and inhomogeneity influence charge-transfer excitons. The project develops novel approaches to map exciton diffusion and distinguishes between localized and mobile excitonic states.
Experimental methods: tip-enhanced Raman spectroscopy (TERS), tip-enhanced photoluminescence (TEPL)
