Thermo-electric method for texturing of glass surfaces

摘要

A thermo-electric method for texturing a glass surface including, for example, simultaneously heating a glass substrate to a temperature less than its glass transition temperature and applying a bias across the glass substrate using a template electrode. The applied bias at the processing temperature induces localized ion migration within the glass, which results in the formation in the glass surface of a negative topographical image of the pattern formed in the electrode.

1. A method for forming texture in a surface of a glass substrate, comprising:
contacting a glass surface of a glass substrate having a glass transition temperature and a template electrode; heating the electrode-contacted glass surface to a temperature at least 200° C. less than the glass transition temperature; and applying a DC bias to the electrode effective to transport ions within the glass surface and form a textured glass surface.
