Atomic‐level structural editing is a promising way for facile synthesis and accurately constructing dielectric/magnetic synergistic attenuated hetero‐units in electromagnetic wave absorbers (EWAs), but it is hard to realize. Herein, utilizing the rapid explosive volume expansion of the CoFe‐bimetallic energetic metallic triazole framework (CoFe@E‐MTF) during the heat treatment, the effective absorption bandwidth and the maximum absorption intensity of a series of atomic CoFe‐inserted hierarchical porous carbon (CoFe@HPC) EWAs can be modified under the diverse synthetic temperature. Under the filler loading of 15 wt%, the fully covered X and Ku bands at 3 and 2.5 mm for CoFe@HPC800 and the superb minimum reflection loss (RLmin) of −53.15 dB and specific reflection loss (SRL) of −101.24 dB mg−1 mm−1 for CoFe@HPC1000 are achieved. More importantly, the single‐atomic chemical bonding among Co─Fe on the nanopores is captured by extended X‐ray absorption fine structure, which reveals the formation mechanism of nanopore‐confined vortical dipoles and magnetic domains. This work heralds the infinite possibilities of atomic editing EWA in the future.

“…Additionally, improved energy resolution and SNR could facilitate the detection of spectroscopic signatures of magnons, which are quanta of collective spin excitations, and their dispersion in momentum space, providing insights into the atomic‐scale 2D magnetic structures in TMDs. [ 184 ] Besides, the current cryogenic temperature utilized in (S)TEM is usually limited to liquid nitrogen temperature, while many quantum physics phenomena in 2D TMD systems can only be observed at temperatures close to 0 K. [ 19 ] Although liquid helium has been introduced into the STEM to achieve lower temperatures around 10 K, [ 205 ] atomic‐scale imaging and spectroscopy are still challenging due to stage instability. Moreover, there is a pressing need for improved MEMS techniques capable of accommodating more intricate external field conditions.…”

Abstract2D transition metal dichalcogenides (TMDs) exhibit remarkable properties that are strongly influenced by their atomic structures, as well as by various types of defects and interfaces that can be precisely engineered and controlled. These features make 2D TMDs and TMD‐based materials highly promising for a wide range of applications in electronics, optoelectronics, magnetism, spintronics, catalysis, energy, etc. By providing a comprehensive approach to understand the structure–property–functionality relationship in materials at the atomic scale, electron microscopy, and spectroscopy techniques have emerged as invaluable tools for studying both the static characteristics and dynamic evolutions of 2D TMDs. In this review, the primary focus lies in exploring intrinsic and artificial structures in TMDs and their heterostructures, along with their corresponding properties, through cutting‐edge aberration‐corrected scanning transmission electron microscopy (STEM) and electron energy loss spectroscopy (EELS). Additionally, recent advancements in the field of in situ visualization and manipulation of 2D TMDs using electron beams are highlighted. It is anticipated that the up‐to‐date overview provided, along with a glimpse into the future development of STEM‐based techniques, will make a substantial contribution to advancing research on 2D materials.
