Two-dimensional hybrid metal halide device allows control of terahertz emissions

Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce.
