Resolving Transient Electron-Phonon Coupling with Time-Resolved Spontaneous Raman Spectroscopy
Guy Reuveni, Maya Levy Greenberg, Matan Menahem +2
Understanding the interaction of charge carriers with lattice vibrations in the quasi-equilibrium regime is crucial for semiconductor functionality. However, the structural signatu…
Anharmonic Fluctuations Govern the Band Gap of Halide Perovskites
Stefan A. Seidl, Xiangzhou Zhu, Guy Reuveni +5
We determine the impact of anharmonic thermal vibrations on the fundamental band gap of CsPbBr, a prototypical model system for the broader class of halide perovskite semicondu…
Static and Dynamic Disorder in Formamidinium Lead Bromide Single Crystals
Guy Reuveni, Yael Diskin-Posner, Christian Gehrmann +8
We show that formamidinium lead bromide is unique among the halide perovskite crystals because its inorganic sub-lattice exhibits intrinsic local static disorder that co-exists wit…
The dielectric response of rock-salt crystals at finite temperatures from first principles
Nimrod Benshalom, Guy Reuveni, Roman Korobko +2
We combine ab initio simulations and Raman scattering measurements to demonstrate explicit anharmonic effects in the temperature dependent dielectric response of a NaCl single crys…
