Volume relaxation of poled glasses: Surface relief enhancement
Journal of Non-Crystalline Solids, 2018•Elsevier
It has been shown that the additional annealing of thermally poled silicate glasses at
temperatures exceeding the glass poling temperature and close to, but below, the glass
transition temperature leads to an essential decrease of the volume of polarized regions
and, as the result, to an increase in the height of the surface relief structures formed by
poling with profiled relief anodic electrode. Thermodynamic and rheological explanations of
the found volume decrease are given.
