Lowering the dose rate during the HRTEM imaging process is one of the best practices to protect the sample from electron beam damage. Different materials respond differently with varying dose rates. In dose-rate-dependent materials, the electron-beam-induced damage increases with increasing dose rate. Radiolysis, heating, and charging are common damage mechanisms in the case of MOFs, zeolites, and organic compounds . In ZIF-8, we didn't find a dose-rate dependency of the critical dose, at least in the range of dose rates from 0.33 to 2.0 e -Å -2 s -1 studied here, as shown in our results in fig.
