Abstract

Abstract : A giant terahertz modulation based on a Ba0.6 Sr0.4 TiO3 –silicon hybrid metamaterial is reported by L. Wu, W. Zhang, and co‐workers on page 2610. The proposed nanoscale Ba0.6 Sr0.4 TiO3 (BST) hybrid metamaterial, delivering a transmission contrast of up to ≈79% due to electrically enabled carrier transport between the ferroelectric thin film and silicon substrate, is promising in developing high‐performance real world photonic devices for terahertz technology.
