Deskripsi
Various applications of terahertz technology require a large number of various terahertz wave control devices. Yet, high efficient and rapid-response terahertz switch is still a great challenge. Here, we introduce a new scheme, based on inorganic perovskite quantum dot (CsPbBr3-QD)-embedded metasurface under different pump laser powers that realize terahertz wave high-speed switching performance. The off–on speed of the presented device achieves 8 MHz. This kind of components provides a new idea and a cost-effective functional solution for manipulating the terahertz waves in emerging terahertz devices and systems.
