From: Structural and configurational properties of nanoconfined monolayer ice from first principles
Instability of the honeycomb network at high isotropic lateral pressures, leading to a spontaneous relaxation to a square network configuration.
The three possible strains to the hexagonal cell are shown by the pairs of green/red/blue arrows; the path given by the green one is followed here. The simulations are performed at d = 6 Å. The pressure is varied linearly from 0 to 5 GPa⋅Å and all the curves are aligned to zero for the unstrained cell.
