Near-field optical investigation of quantum emitters on the nanoscale (C02)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Theoretical Chemistry: Electronic Structure, Dynamics, Simulation
• Term: since 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 398816777

Project C2 will apply non-linear optical nearfield techniques to investigate point defects in hexagonal boron nitride (hBN), which emit single photons. The aim of the project is to employ scattering scanning near-field optical microscopy (sSNOM) to assess the optical emitter response as well as the crystal structure using non-linear plasmon-enhanced techniques such as tip-enhanced Raman spectroscopy (TERS), tip-enhanced coherent anti-Stokes Raman scattering, and tip-enhanced stimulated Raman scattering. Raman scattering thereby allows identifying characteristic and unique fingerprints of the specific hBN defects in question.
