The dielectric response of materials underpins electronics and photonics. Established semiconductor materials have a narrow range of dielectric susceptibility, with low-frequency values on the order of 10. Strong and variable dielectric response in wide-band gap materials is associated with complex crystal structures and heavier elements. Based on underlying chemical trends, we hypothesize that chalcogenides in crystal structures common to complex oxides may feature many highly-polarizable semiconductors. Research on these materials is motivated by fundamental inquiry into electrons and phonons in solids, and by potential applications in photonics, high-frequency communications, and photovoltaics.
