Room-Temperature Exciton-Polariton-Driven Self-Phase Modulation in Planar Perovskite Waveguides

Optical nonlinearities are crucial for advanced photonic technologies since they allow photons to be managed by photons. Exciton-polaritons resulting from strong light-matter coupling are hybrid in nature: they combine the small mass and high coherence of ...

Crystal-Size-Induced Band Gap Tuning in Perovskite Films

Michael Graetzel, Simone Meloni, Wolfgang Richard Tress, Amita Ummadisingu

A comprehensive picture explaining the effect of the crystal size in metal halide perovskite films on their opto-electronic characteristics is currently lacking. We report that perovskite nanocrystallites exhibit a wider band gap due to concurrent quantum ...
