Hybrid Perovskite Terahertz Photoconductive Antenna [PDF]
Nanomaterials, 2021 Hybrid organic–inorganic perovskites, while well examined for photovoltaic applications, remain almost completely unexplored in the terahertz (THz) range. These low-cost hybrid materials are extremely attractive for THz applications because their optoelectronic properties can be chemically engineered with relative ease.
