Abstract
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.
Claims16
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.

A method for forming texture in a surface of a glass substrate, comprising:
- contacting a glass surface of a glass substrate and a template electrode at a temperature ranging from 20° C. to (Tg−200° C.), wherein Tg is the glass transition temperature of the substrate;
- and
- applying a DC bias to the electrode effective to transport ions within the glass substrate and form a textured glass surface.
