Understanding how electrons turn to glass

These electrons, responsible for conducting electrical currents, are unable to reach their lowest energy state due to the way they are geometrically arranged on the material’s crystal lattice.
Slow cooling of conventional glass-forming liquids causes their atoms to organize themselves into regular arrangements, producing a crystallized material.
When the researchers slowly cooled the organic metal they were testing, its frustrated electrons similarly organized into a regular pattern and crystallized. when the material was cooled more quickly, crystallization was avoided and the material’s frustrated electrons re-organized, turning into glass in a similar manner to conventional glass-forming liquids.

The results highlight the universal nature of the liquid-to-glass transition phase.

Future scope: Development of  DVDs or blue ray discs that store data by altering their state of matter from one to another, and of new glass materials.
