Experimental investigations of optical and electrical properties of atomically thin 2D semiconductors and their interactions with plasmonic nanostructures.
Optical microscopy and spectroscopy in the visible – near infrared spectral range. Photoluminescence, Raman, time-correlated single photon counting, lifetime and cryogenic (T=4-500 K) spectroscopy and microscopy of individual plasmonic nanoantenna/2D semiconductor hybrids.
Finite-difference time domain (FDTD) solvers of Maxwell’s equations (Lumerical).
Focus of future research:
- Femtosecond spectroscopy, dynamics, pump-probe experiments and nonlinear optics with hybrid plasmon-exciton nanostructures
- Quantum optical effects, e.g. single photon nonlinearity and photon blockade in nanophotonic systems at room temperature
- Exciton physics and electro-optical effects in van der Waals heterostructures.
