Probing atomic structure of beam-sensitive energy materials in their native states using cryogenic transmission electron microscopes

Summary: Organic–inorganic hybrid perovskite nanoplatelets (NPLs) have emerged as promising materials for solar energy. However, the structural instability under electron beam hinders further probing and understanding of its crystalline structures and defects at the atomic scale. Taking methylammoni...
