N2 - We measure THz (10-90 cm-1, 1-11meV) transmittance through chalcogenide perovskite thin films in the 80-295 K temperature range. SrHfS3, BaZrS3, and BaZrS3 films were deposited on sapphire substrates using magnetron sputtering. The transmittance data provide the complex refractive index of the films. We observe Drude conductivity as well as several phonon features that are temperature dependent. The THz behavior provides new information on the electronic and lattice structure of these new materials.
