Summary

Story summary

New research from the University of Vienna observes the melting of atomically thin silver iodide (AgI) crystals and identifies a rare intermediate hexatic phase.
The hexatic phase combines properties of solid and liquid states and was captured using advanced electron microscopy and neural network analysis.
The study finds that the transition from solid to hexatic is continuous, while the hexatic-to-liquid transition is abrupt, challenging previous theories.
