Fig. 2: Growth characteristics of 2D ice in coexistence with 3D ice.
From: Two-dimensional bilayer ice in coexistence with three-dimensional ice without confinement

a A sequence of snapshots of the coexisting ice growth process (Front view and top view) for ε = 0.5 kcal·mol−1. Dark yellow, light blue, light gray (3.08 ns) and light red balls represent hexagonal ice, cubic ice, 2D ice and solid substrate, respectively. b Density profile of the 2D ice. Density represents the size of 1D density. Height is the size of z axis. c The number of ice molecules versus time. d Phase diagram of liquid water, 2D ice and 3D ice with respect to temperature T and energy parameter ε. Phase diagram consists of liquid water, 2D ice in coexistence with liquid water, 3D ice and 2D-3D coexisting ice.
