The low-pressure phase I of solid hydrogen, which consists of freely rotating molecules on a hexagonal close-packed lattice 2, transforms at pressures of about 110 GPa to the broken-symmetry phase ...

The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice .

Understanding how molecular arrangements within crystals influence their thermal behavior is a fundamental question in ...
