Organic-inorganic halide perovskites have received attention because of their good photovoltaic properties and their thermoelectric properties. Therefore, understanding of the origin of their useful properties are important to design more effective application. Here, we are interested in the lattice dynamics, which possibly affects the electric channel. In this study, we have studied the lattice dynamics of perovskite compounds by using first-principles calculation.
