Nature research paper: Tracking cubic ice at molecular resolution
, Time-lapsed TEM images of one ice Ic crystallite and corresponding selected area FFTs . The corresponding illumination electron beam dose of each image is 47 e. Electron irradiation time for each image is 0.4 s. Facets were indexed as labelled on images. Area I is the single crystalline Ic matrix along zone axis. Area II shows the high density of stacking faults on
) plane based on diffractometry information. Both single-crystalline Ic matrix and the defected area grew over time with no phase transition during the observation time.Supplementary Video 1 Visualization of the defect structure dynamics in ice Ic. Real-time molecular-resolution snapshot TEM records of defects in an -oriented ice Ic crystallite illuminated by 300-kV accelerated high-energy electron beam for 10 s, showing the slip and interlayer transfer behaviour of defective ice layers on close-packed planes. The bright spots in the video frame indicate the water-dimer column positions in the ice Ic lattice.
