Hybrid perovskites formed of both organic and inorganic materials in the same crystal unit provide new functionalities otherwise not possible in either organic and inorganic components alone. Due to the ionic nature of these materials, electrons and phonons are strongly coupled and coherent phonons could be excited with ultrashort laser pulses. In this study, using transient absorption spectroscopy measurements, we show that these coherent phonons could be used to manipulate charge transfer in a two-dimensional double perovskite. Findings of this study may serve as a new degree of freedom to consider when designing materials for optoelectronic applications where charge transfer kinetics are crucial.
