Transmission electron microscopy

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher spatial resolution than light microscopy.

    Conversion electrodes possess high energy density but suffer a rapid capacity loss over cycling compared to their intercalation equivalents. Here the authors reveal the microscopic origin of the fading behavior, showing that the formation and augmentation of passivation layers are responsible.

    Methylammonium lead halide perovskites have great potential for optoelectronic applications but are prone to degradation. Here the authors show that degradation can occur through clustering of Pb containing defects at the grain boundaries while concurrent formation of PbI2 blocks further reactions, suggesting a strategy for passivation.

    Atomically precise measurements in 2D materials can be used to quantify the effects of energetic electron irradiation. In this Perspective, we discuss how understanding of electron–matter interactions can help to stimulate the development of quantitative models that are generalizable to a wide range of materials.

    Cracks propagate preferentially along grain boundaries, but what happens exactly at the atomic scale remains unclear. Here, the authors combine atomic-scale observations and first-principles calculations to show local coordination chemistry at a dopant-segregated alumina grain boundary core dictates the atomic bond-breaking path.
