Active THz Devices Using Hybrid Lead-Halide Perovskites

摘要

We demonstrate the use of organic-inorganic lead-halide perovskites to create active terahertz (THz) devices. Specifically, we use both two-dimensional and three-dimensional hybrid lead halide perovskites to selectively modulate the THz transmission properties. The devices require deposition of the perovskite directly onto a silicon substrate, but allow for control of THz transmission properties using a simple halogen lamp and a set of color filters.
