Reo Sato, Kentaro Noguchi, Hiroyuki Koshida, Atsuki Ishibashi and Tetsuya Hama : Three-Step Growth of Vapor-Deposited Ice under Mesospheric Temperature and Water Vapor Conditions., The Journal of Physical Chemistry Letters, 16, 30, 7675-7684, 2025. (Summary) Polar mesospheric clouds provide clues to physicochemical processes in the mesosphere and lower thermosphere. However, the heterogeneous nucleation and growth processes of water ice under polar mesospheric conditions are poorly understood, especially at the nanoscale. This study used reflection high-energy electron diffraction and infrared reflection-absorption spectroscopy to analyze the structure of vapor-deposited ice at polar mesospheric temperature (120 K) under vapor pressure (10-6 Pa) conditions. The ice appeared to grow in three steps during vapor deposition, being amorphous water for the first 15 nm, then cubic ice up to 50 nm, and finally hexagonal ice subsequently. This three-step growth suggests that the three observed phases can coexist in polar mesospheric clouds, depending on the thickness of water ice. The finding of the three-step growth also shows that the Ostwald rule of stages can hold for vapor-deposited ice at low temperature.
