Electromagnetic Response and Energy Conversion for Functions and Devices in Low‐Dimensional Materials

Low‐dimensional materials have been long sought after for their particular electromagnetic (EM) functions, with promising applications in EM wave absorbing and shielding, communicating and imaging, sensing and detecting, driving and actuating, etc. Herein, across the whole EM spectrum, low‐dimensional EM functional materials and devices are highly focused on. The crystal engineering and function‐guiding features addressed relate to crystal and electronic structures, EM responses and properties, energy conversion, as well as EM wave absorbing and shielding. Moreover, insight is given into this rapidly broadening field, the main challenges are proposed and future directions are predicted. Electromagnetic response and energy conversion for functions and devices of low‐dimensional materials are systematically summarized. The crystal and electronic structures are described, and crystal engineering and function‐guiding features are highlighted. Importantly, the electromagnetic functions and devices are demonstrated with a prediction of the most prospective opportunities and directions for the future.
