Unraveling the exciton binding energy and the dielectric constant in single-crystal methylammonium lead triiodide perovskite

We have accurately determined the exciton binding energy and reduced mass of single crystals of methylammonium lead triiodide using magneto-reflectivity at very high magnetic fields. The single crystal has excellent optical properties with a narrow line width of ∼3 meV for the excitonic transitions...
