Popis:	Understanding the controllability of the THz-wave absorption property of organic–inorganic hybrid perovskite (OHP) thin films is necessary to advance the THz-based application field. Here, we found the correlation of THz-wave absorption property by different halogen elements in FAPb(Br, I)-based hybrid perovskite thin films fabricated by sequential vacuum evaporation. We confirm that the selection of halogen elements and their concentration ratio can be changed to systematically control the THz conductivity property.
