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.
