میکروسکوپ الکترونی عبوری روبشی
AFM, STEM, AC- TEM and CFM can obtain 2D or even 3D images of MOF, and HRTEM can characterize the spatial structure of MOF at the atomic level.
In addition, scanning transmission electron microscopy (STEM), which has both SEM and TEM functions, has gradually entered the line of sight.
Recently, Zhang et al. proposed that the rapid development of aberration-corrected transmission electron microscopy (AC- TEM) in TEM and STEM modes has pushed the resolution below 1 A.
What's more attractive is that the 2D STEM image can be integrated into a data set to get
''4D STEM" [235].
