摘要
The development of the aberration correction technique has enabled atomic resolution imaging in scanning transmission electron microscopy (STEM) under low accelerating voltages and pushed the detection limit of STEM-based imaging and spectroscopy analysis down to the single-atom level. The so-called "single-atom electron microscopy" brings new opportunities to study the structure-property relationship in energy-related nanomaterials at the atomic scale. In this review, we will firstly summarize some recent advances in low-voltage STEM imaging and spectroscopy with single-atom sensitivity, including emerging techniques such as STEM-DPC imaging andin situSTEM, by using two-dimensional (2D) materials as model systems. We will then discuss the application of these single-atom electron microscopy techniques to more complex energy materialsviaspecific examples. These powerful and comprehensive capabilities of aberration-corrected STEM with single-atom sensitivity have proven to be invaluable for unveiling the origins of functionalities of energy-related nanomaterials and guiding the design of novel materials with desired performance.
