Nanoscale morphologies resulting from surface treatments of display glass in vacuum

Radiation‐Induced Surface Conductivity in an Alkaline‐Earth Boroaluminosilicate Glass Measured with Elevated‐Temperature Scanning Probe Microscopy

“…7 indicates that the morphology of the surface is not significantly changed by the 325‐nm radiation. Both images show distinct globular features with nanometer dimensions that are characteristic of fracture surfaces of Code 1737 17 and calcium aluminosilicates. Although taken with different AFM tips, the structural features of the two images are quite similar.…”

“…Hence, we conclude that the 325‐nm radiation has not produced large‐scale transformations at the glass surface where the conductivity is measured. In contrast, electron‐beam irradiation substantially alters the morphology of the glass surface, 17 as well as inducing a surface conductivity that persists for several days and that allows imaging with STM at elevated temperatures (the details of electron‐beam‐induced conductivity are to be treated elsewhere). Characterization of radiation‐induced changes in composition and in the bonding character at the surface is still needed to determine how permanently the glass structure and chemistry are altered for both near‐UV and electron‐beam irradiation.…”
