Fig. 2

a TEM image of a fully-grown hexagonal ice crystallite showing that faceted surfaces had a hexagon morphology. b High-magnification TEM images and the corresponding FFT of selected areas as numbered in (a), depicting hexagonal ice surface structure. c Illustration of the deduced hexagonal ice structure showing the 〈001〉 crystallography direction-oriented ice Ih crystallite partially wrapped by a 〈111〉-oriented ice Ic in the habit surface. TEM images are displayed in blue color. Scale bar for FFTs: 2 nm−1 (shared across panels).
