Cover Photograph: Glasses in the Al 2 O 3 ‐SiO 2 system are notoriously difficult to form without phase‐separation or crystallization, as shown for a composition quenched from the melt along Path A. By instead subjecting alkali aluminosilicate glasses to a poling process under electric‐fields at low temperature (Path B), surface depletion layers of the same composition are formed that circumvent these issues, and moreover show unique structural characteristics within the glassy layer.
