Event Picture:

Cs2AgBiBr6 is a member of the halide double perovskite family with high photovoltaic efficiency. We have synthesized single crystals of Cs2AgBiBr6 from solution using a controlled cooling method. The THz vibrational modes near band gap resonance were investigated by temperature dependent Raman scattering, supplemented by optical transmission measurements of the band gap itself. With a 532.8 nm laser the mode at 5.36 THz shows a very strong resonance peaked at 30 K.
