From: Bismuth and antimony-based oxyhalides and chalcohalides as potential optoelectronic materials
Calculated dielectric constants (ε) of the considered bismuth/antimony oxyhalides and chalcohalides. We show total static dielectric constant (εst) and the component from phonon contribution (εphonon). Note that these compounds have generally high dielectric constants, mostly due to large phonon contributions
